Bug ID: 501775
Summary: Konsole crashes when saving file in Firefox via the
file picker portal
Classification: Applications
Product: konsole
Version: 24.12.3
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: konsole-de...@kde.org
Reporter: accounts+...@chiller3.com
Target Milestone: ---
SUMMARY
This is a bit of an odd one. When I save a file in Firefox with the KDE file
picker via XDG portals, Konsole will sometimes crash. The issue is not always
reproducible, but I've encountered it 5 times so far. I've attached a backtrace
with debug symbols below.
This only started happening very recently. Based on the timestamps in
coredumpctl, it very likely started happening after Fedora 41 upgraded the
frameworks from 6.11.0 to 6.12.0. I do see kconfig in the backtrace, but I
wasn't sure if I should report the issue for konsole or kconfig since konsole
is the only KDE application that's been crashing on my system.
STEPS TO REPRODUCE
1. If Firefox isn't already using XDG portals, set
widget.use-xdg-desktop-portal.file-picker=1 in about:config
2. Go to https://kde.org
3. Right click any image and save it
4. Hit the save button in the KDE file picker dialog
OBSERVED RESULT
Konsole sometimes crashes (though Firefox is fine and the file saves
successfully)
EXPECTED RESULT
Konsole should not crash
