Summary: Dolphin crashed when overing context menu->activities
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: m_ta...@yahoo.com
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:
Hi,
Dolphin is crashing when the mouse goes through the "context menu ->
activities" item...funny thing is, it only happens if dolphin is in my second
screen. It doesn't crash on the first screen.
The crash can be reproduced every time.
-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
