Bug ID: 395099
Summary: Plasma falls when search on start menu
Product: plasmashell
Version: 5.12.5
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: vitaly.khatlamadzhiyan+...@orbitsoft.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.12.5)
Qt Version: 5.9.4
Frameworks Version: 5.46.0
Operating System: Linux 4.16.13-200.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"
-- Information about the crash:
- What I was doing when the application crashed:
- Unusual behavior I noticed:
Just call menu (Alt+F1) and type.
But do it quick.
For example, I offen launch google chrome from start menu.
For it I type "chome", but sometimes after "ch" Plasma falls.
If I wait a little after the start menu shown, no falls.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
