*** This bug has been marked as a duplicate of bug 392591 ***
Created attachment 119041 [details] New crash information added by DrKonqi plasma-discover (5.15.3) using Qt 5.11.1 - What I was doing when the application crashed: I used the plasma quick launch (alt-space) to search and selected 'Software Center | Get KTeaTimer' after typing 'ktea'. - Unusual behavior I noticed: The applicaiton renders a frame of a window but before it crashes before the content appears. This happens 100% of the time on my system. -- Backtrace (Reduced): #6 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 #7 0x00007f0e0922f535 in __GI_abort () at abort.c:79 #8 0x00007f0e096028d7 in QMessageLogger::fatal(char const*, ...) const () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #9 0x00007f0e0b1d8eed in QSGRenderLoop::handleContextCreationFailure(QQuickWindow*, bool) () from /usr/lib/x86_64-linux-gnu/libQt5Quick.so.5 [...] #12 0x00007f0e0a242b05 in QWindow::event(QEvent*) () from /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5
