-- Information about the crash:
- What I was doing when the application crashed:
I assigned meta+a shortcut to plasma-pa applet, then I assigned the same shortcut to Touchpad applet, tried to open "Configure audio
volume..." via context menu of plasma-pa applet and Plasma crashed.

The reporter is unsure if this crash is reproducible.

Comment 1 Nate Graham 2021-03-21 14:43:31 UTC

When I try to assign Meta+A to the touchpad applet when the audio applet already has that shortcut, I see a shortcut conflict dialog that prompts me to re-assign one of them. Did you see that?

Comment 2 Patrick Silva 2021-03-21 15:29:56 UTC

I think I saw the conflict dialog, I don't remember well though.
I was trying to find the exact steps to reproduce a problem with keyboard shortcut (reported as bug 434721) by repeatedly assigning shortcuts to several applets and this Plasma crash occured just once.

Comment 3 Nate Graham 2021-03-21 16:03:21 UTC

OK thanks.
