Description PC LX 2018-02-27 19:42:24 CET

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.

There are over 100 commits since version 0.11.1, including lots of fixes but, after reading the change log, I can't confirm if this particular issue is fixed by any of those commits.
