And what version of kglobalaccel do you have installed? This looks very similar to bug#406426, that was a regression in 5.57 though and KUbuntu 19.04 ships with 5.56 AFAICS.

It must be that bug then, since I am using 5.57 from Kubuntu backports. I will try to figure out how to force the regular version
*** This bug has been marked as a duplicate of bug 406426 ***
FTR, it seems that Kubuntu Backports have been updated to KF 5.58.0 recently, where the crash should be fixed.
