Bug ID: 387886
Summary: systemsettings segfault on backspace navigation
Product: systemsettings
Version: 5.11.3
Platform: RedHat RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: sidebarview
Assignee: notm...@gmail.com
Reporter: axo...@riseup.net
Target Milestone: ---
Created attachment 109367
--> https://bugs.kde.org/attachment.cgi?id=109367&action=edit
plasmashell backtrace
Application: systemsettings5 (5.11.3)
Qt Version: 5.9.2
Frameworks Version: 5.40.0
Operating System: Linux 4.14.3-300.fc27.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I've tested this a few times, it is repeatable on Fedora 27 and Arch. When you
load a panel on the right, by navigating on the left, and then use the back
button to return to the previous level of navigation on the left suddenly while
controls are still being drawn (I think this matters), systemsettings5 and
plasmashell may die.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
