Bug ID: 358819
Summary: Plasmashell - very frequent SIGSEGV when closing any
windows
Product: plasmashell
Version: 5.5.4
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: m...@op.pl
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.4)
(Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.2.5-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
Just closed a window. Or it was closed by an application. Generally closing
windows triggers this bug.
I saw many duplicates posted here, but they didn't have full debugging
information, so I complied plasmashell from AUR (in Arch) to help with
debugging.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plazma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
