Bug ID: 359749
Summary: kwin_x11 crash when iceweasel restoring multiple
windows
Product: kwin
Version: 5.5.4
Platform: Debian unstable
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: arthur.ma...@internode.on.net
Application: kwin_x11 (5.5.4)
Qt Version: 5.5.1
Operating System: Linux 4.5.0-rc5+ x86_64
Distribution: Debian GNU/Linux unstable (sid)
-- Information about the crash:
- What I was doing when the application crashed:
starting iceweasel, which was attempting to restore several windows. Unlike
previous times, the crash handler worked and the resulting back trace was
declared useful.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
