Description Ilgaz Öcal 2021-06-20 16:18:43 UTC 
SUMMARY


STEPS TO REPRODUCE
1. Install any flatpak from flathub.org
2. Run it (e.g. remmina)
3. It will show a warning once you switch to another application "running in background", click "allow"

OBSERVED RESULT
xdg-desktop-portal.kde crashes (no report e-mail given so it isn't reported)

EXPECTED RESULT
It should normally quit

Comment 1 Alois Wohlschlager 2021-06-23 13:58:47 UTC 
I don't see an "allow" button, do you mean the close button or the "find out more" button?

Please try to create a backtrace again after cleaning the debuginfod cache (sometimes, stale or corrupt entries there seem to make gdb hang).

Backtrace

I managed to get a backtrace now. Attached. About "Allow" in prompt: It first alerts you saying application is running in background. You click "Find out more" and secondary prompt appears having 2 options "allow" and "force quit".

Background portal: avoid crash when allowing app to run in background

We need to return as soon as possible from the notification callback, otherwise it can
happen that the notification is closed and deleted while we block the callback with
a message dialog.
