Backtrace

I'm using KF5 libs from Project5-Neon on Kubuntu 14.04. If I try to use KMessageBox::information (or any other KMessageBox function), the application crashes. The equivalent QMessageBox does not cause a crash. Attached is the backtrace and also a simple project that illustrates this crash.

Comment 3 Christoph Feck 2014-07-18 14:52:19 UTC 
As a workaround, do not use phonon-backend-vlc, or disable use of phonon for knotify sound notifications (I simply use a command line player instead).
Comment 4 Jasem Mutlaq 2014-07-18 14:54:20 UTC 
Great thanks, any idea on how to do either of those? I'm just using KF5 from project-neon5, is there some config file I need to edit somewhere?
Comment 5 Jasem Mutlaq 2014-07-18 15:01:24 UTC 
ok, I just removed project-neon5-phonon4qt5-vlc and project-neon5-phonon5-vlc and the crash is done! Thanks!

Running "/usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins/" as root fixes the crash
