Bug ID: 375619
Summary: plasmashell crashes from time to time without apparent
reason
Product: plasmashell
Version: 5.5.5
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: krzysztof.ci...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.5.5)
Qt Version: 5.5.1
Operating System: Linux 4.4.8-200.fc22.i686+PAE i686
Distribution: "Fedora release 22 (Twenty Two)"
-- Information about the crash:
- What I was doing when the application crashed:
just browsing Internet in Chrome
This error happens once every few days, but in different situations - usually
when doing something unrelated to plasmashell, i.e. within different programs
and not when doing something e.g. on the plasmashell panel.
-- Backtrace:
Application: Plazma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
