Comment 1 Kai Uwe Broulik 2020-03-17 08:25:28 UTC 
Crashes in the gtk2 style of qtstyleplugins, can't reproduce, though.
Can you install debug symbols for this? Also, when you run it from terminal (e.g. kcmshell5 style), is there any unusual debug output? Here it crashed the first time because of incompatible Qt version (system Qt different from plug-in). After a rebuild it worked.
Comment 2 Alberto Castillo G. 2020-03-17 17:14:57 UTC 
As Kai mentioned, running from terminal showed incompatible versions. Rebuilt qt5-styleplugins and now it's working fine.
Comment 3 Kai Uwe Broulik 2020-03-18 07:51:40 UTC 
Alright, thanks for reporting back!
