Bug ID: 385359
Summary: Plasmashell crashes repeatedly
Product: plasmashell
Version: 5.10.5
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
Application: plasmashell (5.10.5)
Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.8.0-53-generic x86_64
Distribution: KDE neon User Edition 5.10
-- Information about the crash:
- What I was doing when the application crashed:
Nothing in particular except this crash happened after I installed qt5-default
package (5.9.1+dfsg-2+16.04+xenial+build25) from
"http://archive.neon.kde.org/user xenial/main amd64 Packages" Neon user-edition
repo.
- Unusual behavior I noticed:
The crash happens every 10-15 minutes after logging in.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
