    Description

      Original bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=790825

      Qt5 apps seems to crash when a laptop is waked up from suspension/undocking a laptop. Sebastian Ramacher, Debian VLC's maintainer, came up with a test code [testc] which I'm attaching.

      [testc] <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=790825#22>

      As he does not has a docking station he managed to reproduce it by waking up from suspend.

      I'm also attaching a backtrace from that example program.
