Description of problem:

I have recently upgraded the Qt/KDE/Plasma packages to those currently in testing. Before this upgrade, the lxqt-panel was working. After this upgrade, the lxqt-panel crashes on start.

From the backtrace, I think it is an issue in lxqt-panel and not Qt so I reported it to lxqt people.
