Description Germano Massullo 2017-11-25 09:48:52 UTC 
Version is 5.10.5, not 5.11.1, I had to select that because there was no 5.10 value


Application: kwin_x11 (5.10.5)

Qt Version: 5.9.2
Frameworks Version: 5.38.0
Operating System: Linux 4.13.13-200.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
- What I was doing when the application crashed:
I logged into Plasma, when KWin crashed during Plasma loading

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
84	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
