wxWidgets doesn't use dbus either, except for WebView.  wxMaxima doesn't 
use WebView does it?

In any case, I can't reproduce this in unstable.  So it's either been 
fixed or there is something else required to reproduce.

Can someone who can reproduce this run it under gdb and get a stack trace 
to see where that g_dbus_proxy_new() call is coming from?

See, e.g.:

Thanks,
Scott
