#161652 — KDE "libplasmacomponentsplugin.so is not a valid Qt plugin" after crossgrade?

Message-ID<qDM2B-8kP-7@gated-at.bofh.it>
Hello

I've just crossgraded my desktop computer from i386 to amd64, using the wiki
recipe and got everything working so far.

The only problem:
On the lower right corner I have to white/red "do not enter road sign icons"
where "Notifications", "System Tray" and the icons of minimized music players 
etc used to be. Also when clicking on the "bean" icon and "+ Add Widgets",
I get a completely empty selection.

In my ~/.xsession-errors I spot a couple of relating messages:

  plasma-desktop(11613)/libplasma Plasma::DeclarativeWidgetPrivate::errorPrint: "file:///usr/share/kde4/apps/plasma/packages/org.kde.desktop.widgetexplorer/contents/ui/main.qml
  Error loading QML file.
  21: plugin cannot be loaded for module "org.kde.plasma.components": The file '/usr/lib/kde4/imports/org/kde/plasma/components/libplasmacomponentsplugin.so' is not a valid Qt plugin.
  " 
  QDeclarativeComponent: Component is not ready
 ...
  plasma-desktop(11613)/plasma StatusNotifierItemSource::refreshCallback: DBusMenu disabled for this application 
  file:///usr/share/kde4/apps/plasma/packages/org.kde.plasma.tasks/contents/ui/Task.qml:276: Error: Qt.createQmlObject() failed to create object:     file:///usr/share/kde4/apps/plasma/packages/org.kde.plasma.tasks/contents/ui/inline:1:1: plugin cannot be loaded for module "org.kde.plasma.components": The file '/usr/lib/kde4/imports/org/kde/plasma/components/libplasmacomponentsplugin.so' is not a valid Qt plugin.
  QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

I already
* stopped KDM
* purged every package from architecture i386
* purged every QT, KDE, KDM related package
* made sure that /usr/lib/kde4 was empty
* moved away ~/.local and ~/.kde
* reinstalled "kde-plasma-desktop"
* restarted KDM

But the problem persists. The shared library is there and looks ok, i.e. 
with no missing linker dependencies:

I thought it was rather clear, but....

You can "*strongly* suggest" whatever you want; it is your perogative.
It doesn't imply anyone should take account of the suggestion.

The rules setting boundaries on what is posted here are not set by users
but from On High. Grumbles are probably unlikely to alter the age-old
tradition of posting information relevant to a problem.

You didn't say how large this "Massive snip" was.

It would have been quite clear had you seized on the obvious 
echo of Milton, and posted instead

"They also do not infringe who only post what the Listmaster 
allows."

Having posted "o’er Land and Ocean" I thought I had done my bit.

Most lists discourage posts of the length in question.

All it takes is looking at the quoted message. You can do this as easily
as I.

OK. I did. It's 16K (headers and all). The sum of your messages in this
thread amounts to 7.8K -- just trying to impose your opinion. I think
that's enough: your opinion is now clear enough, some others disagree.

(I, for one. I've solved many a problem by finding relevant mailing
list archive entries -- yes, often older than 1 year. Sometimes by
an indexed error message -- which wouldn't have been indexed in
pastebin [genuine question: does a pastebin entry have a back-link
to the relevant discussion?]. No, I strongly disagree with you).

Sure, there must be a limit for included stuff. For me, it's *far*
beyond 16K.

Somewhere between 100K and 1M perhaps.

Yes.  But this one, except in the persons of you and Felix, doesn't.  And the 
archives are more complete if people do post inline.

Many lists do not have public archives.

The few individuals who think they run the list have set the rules to
make sure nothing is ever posted to pastebin.

Primarily because what is available on pastebin today may not be there in the future, thus rendering messages that reference it somewhat less than useful.

The duration can be specified, although it can't be more than 1(?) year..

I don't know..but maybe right-click in the system-tray and choose the 
system-tray-settings and see if you can find something there!?!

I can do right click on the system-tray and choose "panel options" and choose
"add widgets" there or click "panel settings" and end up in the same menu where
I can adjust the height of the panel as when clicking the "bean icon".
In either way, the list of widgets stay empty but everything else does work.

I tried adding a new user and use that to log in. There, the menu does work
just fine. So apparently there is something in my $HOME that causes the
problems. I'll try to narrow it down during the next lunch breaks :-)

best regards,

Hello

Just for the archives, removing ~/.config/Trolltech.conf fixed the problems.

I don't know what this file is for but it seems to be some kind of cache
for the locations of certain libraries. Too bad that it also contained the 
architecture of those libs:

	$ head ~/.config/Trolltech.conf 
	[Qt%20Plugin%20Cache%204.8.false]
	usr\lib\kde4\plugins\gui_platform\libkde.so=40806, 0, x86_64 linux g++-4 full-config, 2014-11-07T10:21:26
