Comment 1 David Edmundson 2022-06-27 15:28:01 UTC
This doesn't match up with your description. 

>#51 0x00007f49eec40ef5 in __run_exit_handlers (status=0, listp=0x7f49eedfd778 <__exit_funcs>, run_list_atexit=run_list_atexit@entry=true, run_dtors=run_dtors@entry=true) at exit.c:113

It implies we have two bugs

 - A surprise forced exit.
 - A crash during a surprise exit
Comment 2 Nate Graham 2022-06-28 16:17:10 UTC
Cannot reproduce; dragging a group of Konsole windows onto another virtual desktop in the pager doesn't do anything for me, but it also doesn't make Plasma crash.
