Bug ID: 522609
Summary: Crash on logout with Firefox open
Classification: Plasma
Product: xdg-desktop-portal-kde
Version First 6.6.5
Reported In:
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
DESCRIPTION
When I open Firefox (installed via Discover, snap package), then log out and
log back in, the xdg-desktop-portal-kde service crashes, which is indicated by
a pop-up in the right-lower corner.
STEPS TO REPRODUCE
1. Start the PC
2. Open Firefox
3. Log out
4. Log in
OBSERVED RESULT
xdg-desktop-portal-kde service crashes. When I open Firefox again, it takes
significantly longer to start up and the style of the window messes up. For
instance, the system dark theme is not respected (the window is white), the
minimize/maximize/close arrows are missing/have other style etc. Everything
returns back to normal after a restart.
EXPECTED RESULT
Service doesn't crash, Firefox doesn't change its window style.
