Bug ID: 386083
Summary: Kwin crashes after closing Gwenview with unsaved
changes
Product: kwin
Version: unspecified
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: raf...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.8.6)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.90-18.32-default x86_64
Distribution: "openSUSE Leap 42.2"
-- Information about the crash:
- What I was doing when the application crashed:
Kwin error appears every time when I try to close Gwenview (16.08.2) with
unsaved changes and in the popup I click on "Save all changes" button.
In the console there was no trace - the only response before the crash and
probably not linked with it): QWidget::setWindowModified: The window title does
not contain a '[*]' placeholder
---------
Gwenview version: 16.08.2
Plasma version: 5.8.6
KDE frameworks: 5.26.0
Qt 5.6.1
xcb
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
