Bug ID: 415762
Summary: Exiting the session in a Yakuake tab sometimes crash
Yakuake
Product: yakuake
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: h...@kde.org
Reporter: o...@geek.co.il
Target Milestone: ---
Application: yakuake (3.0.5+)
Qt Version: 5.12.4
Frameworks Version: 5.66.0
Operating System: Linux 5.3.0-25-generic x86_64
Distribution: Ubuntu 19.10
-- Information about the crash:
- What I was doing when the application crashed:
using CTRL+d to log out of one of the tabs in Yakuake, with the purpose of
closing that tab.
Using KCI unstable yakuake 19.12.0+p19.10+git20191226.2305-0 and konsole-kpart
4:19.12.0+p19.10+git20191226.2307-0
The crash reporting assistant suggested a lot of duplicates for this behavior,
but all I saw were fixed in KDE/Qt 4. This is a new one for me, and I haven't
seen it before, so I'm guessing its a regression in current git master.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
