Application: kwin_x11 (5.8.4) Qt Version: 5.7.0 Frameworks Version: 5.28.0 Operating System: Linux 4.8.11-1-ARCH x86_64 Distribution: "Arch Linux" -- Information about the crash: Arch Linux with KDE-Unstable repository. - What I was doing when the application crashed: After executing makehuman (compiled from hg version), kwin crashes and screen begins to flash. - Unusual behavior I noticed: Screen flashing. It seems that KWin tries to restart but failed. After exiting makehuman I could restart KWin. The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

Unfortunately the backtrace is (as always with Arch) lacking debug symbols. We see that it crashes, but not where and why. There is nothing we can do to investigate.
