Description Magnus Boman 2019-06-14 07:32:45 UTC
Application: kwin_x11 (5.16.0)

Qt Version: 5.12.3
Frameworks Version: 5.59.0
Operating System: Linux 5.1.9-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

While doing casual browsing and chatting, I clicked (not double clicked to open) a file in Dolphin, and what followed was PC freezing (music still playing), but recovering ~20 seconds later.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace.
