Bug ID: 498456
Summary: "Setup Window Shortcut" can be triggered twice,
causing crash
Classification: Plasma
Product: kwin
Version: 6.2.5
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Created attachment 177251
--> https://bugs.kde.org/attachment.cgi?id=177251&action=edit
Backtrace. Missing a few debug symbols. Lines #7 and #8 in Thread 1 seem like
the important part.
SUMMARY
If you have a shortcut configured to activate "Setup Window Shortcut", you can
activate it while the dialog box to setup a window shortcut is open, which
causes KWin to crash.
I've encountered this problem on occasion; I think it's because I have a
wireless keyboard and it occasionally sends a keypress twice.
STEPS TO REPRODUCE
1. Add a custom window shortcut for "Setup Window Shortcut" (e.g. setting it to
Meta+Return)
2. Focus on a window
3. Hit the shortcut twice in a row
Alternatively, you can use a shortcut to activate the Window Operations Menu
and select "Setup Window Shortcut" from there.
OBSERVED RESULT
Upon pressing the shortcut a second time, KWin freezes for a bit, then crashes
and restarts.
EXPECTED RESULT
Second press of the shortcut should be ignored.

ADDITIONAL INFORMATION
>From looking around in the source code (kwin/src/useractions.cpp, line 1081), I
believe this comes from a failed assert?
This seems to be confirmed in the backtrace (lines marked #7 and #8 in Thread
1). I didn't get enough debug symbols to fill out the full backtrace, but the
ones I'm missing don't seem to be relevant (though I can install more if
needed).
