Bug ID: 367862
Summary: kwin crash when I first run firefox as a different
user after login
Product: kwin
Version: 5.6.5
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: devia...@gmail.com
Application: kwin_x11 (5.6.5)
(Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.23.0
Operating System: Linux 4.0.9-gentoo-gnu20160422 x86_64
Distribution: "NAME=Gentoo"
-- Information about the crash:
- What I was doing when the application crashed:
I logged in, then started konsole using alt+f2 (it started norramlly), then
started firefox as a different user from konsole using kdesu. At this point,
firefox started, but kwin crashed with segfault.
Also, (this is probably another bug in crash reporter), when I try to suggest
duplicates, the crash reporter first allows me to do so (when I browse a
specific report and press the button saying the crash is related), but later,
when I close the related report and click "next", the crash reporter says that
I didn't select any related reports (and allows ether to stay on the page with
the possible duplicates, or to claim that there are no real duplicates).
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
