Bug ID: 391712
Summary: Application Launcher crashes plasma
Product: plasmashell
Version: 5.12.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: p.r.worr...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.12.3)
Qt Version: 5.9.4
Frameworks Version: 5.43.0
Operating System: Linux 4.15.0-10-generic x86_64
Distribution: Ubuntu Bionic Beaver (development branch)
-- Information about the crash:
On a desktop PC, 64-bit, AMD A6-6400K APU with Radeon graphics
Since upgrading from 17.10 to 18.04 Beta 1:
- What I was doing when the application crashed:
Logged in, with no applications started, clicked on Application Launcher button
on the default panel, causes plasma to crash. After plasma restarts, clicking
Application Launcher causes another crash.
- Unusual behavior I noticed:
Screen went black and panel disappeared. Both returned after a few seconds
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
