Bug ID: 378723
Summary: Dolphin crashes while logging out.
Product: dolphin
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: jodr...@live.com
Target Milestone: ---
As the title says. Have a dolphin instance running then log out. You'll get a
crash window instead of dolphin ending cleanly.
Here is the trace i managed to get:
Application: dolphin (dolphin), signal: Segmentation fault
