Bug ID: 362637
Summary: Dolphin crashed after activating the window
Product: dolphin
Version: 15.12.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: planesh...@gmx.net
Application: dolphin (15.12.3)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-21-generic x86_64
Distribution: Ubuntu 16.04 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Clicked the window to activate it. Also happened when accessing a dolphin
window via Alt-Tab. Seems to happen more often, the older the window gets with
windows that were open when the computer went to sleep being the most likely to
crash. This is, however, not guaranteed and neither are windows safe from
crashing before going to sleep.
I have not yet observed a clear pattern but it started with the recent major
kubuntu upgrade.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
