So... the open actually *worked*.

But then obexd claimed the open *failed*.

If obexd doesn't like the path that you've given it, due to too-loose
permissions or whatever, it ought to give a clearer message to indicate
this.

In the absence of a useful error message, you could either source-dive
into obexd and try to figure out what it's actually doing... or you could
*guess* (as I am currently guessing) that it's complaining about
too-loose permissions, and then look at all the permissions of all the
subdirectories along the /home-lisa/user/Downloads path, and see if one
of them is group-writable or world-writable.  If so, fix it, and see if
that makes the problem go away.
