Taking a look into it, I seems very likely, that the following code is
causing the crash:
PackageSearch->setWindowIcon(QIcon(QString::fromUtf8("../icons/packagesearch.png")));
and it crashes only if packagesearch.png is not available in ../icons/.
This used to work fine in earlier versions of QT (up to 4.0.1) and
probably should not lead to a crash. The line was created in from a ui
file, and I had it there to have a nice symbol when editing the file in
the designer. Later in the code I am setting the icon to something that
works for the normal installation.
So a quick fix for packagesearch is, to simply remove the reference to
the icon from the ui file. However I think it is still no the
appropriate thing to crash (and it seems not to do so on amd64). Perhaps
a bug report to Trolltech is due?
Note that I was not able to verify my thesis, because currently I can't
compile with the latest QT due to bug #346603.
Best regards
Ben
