Hello Nate,

Are you sure ?
I cannot reproduce this crash in Kubuntu 22.04 LTS (even with Kubuntu backports installed, Plasma 5.24.7 ) 
neither in Opensuse Leap 15.3 (Plasma 5.24.4).
So I presume it's distro related. 
I am also trying to contact the package builder for Debian 11. as it's not officially supported by Debian.

Comment 3 Nate Graham 2023-02-13 16:33:45 UTC 
Those are both older versions of Plasma, so I don't see how they're related to my assertion that it's fixed in 5.27, which is newer. :)

If 5.27 LTS is released, 5.24 LTS is no longer supported  ? I prefer LTS releases with stable user experience , but I guess there are several unfixed bugs in  5.24 LTS right ? How can I prove this is an unfixed bug ? I would like to use Plasma 5.24 with Debian 11 until Debian12 is released later this year. (hopefully with 5.27)
