Bug ID: 396506
Summary: KWin crash after starting Mozilla Firefox
Product: kwin
Version: 5.8.9
Platform: Mint (Ubuntu based)
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: di...@axx.it
Target Milestone: ---
Application: kwin_x11 (5.8.9)
Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.15.0-24-generic x86_64
Distribution: Linux Mint 18.3 Sylvia
-- Information about the crash:
- What I was doing when the application crashed:
Starting Firefox
- Unusual behavior I noticed:
Lately KDE hasn't been working fine. I had to switch off Bliss because some
applications' menus weren't working (i.e. KTorrent, Amarok...); even after that
Firefox menus on the top-right aren't working, and the security status button
on the left of the address bar isn't showing the usual window; also,
gksu/gksudo now just seems to freeze X until I press Esc.
- Custom settings of the application:
Due to the aforementioned bugs I changed a bunch of themes all at once. That's
when I started noticing KWin crashes.
Also, I have KDE set up to start Firefox on login.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
