All Krita 4.* versions in my Leap 42.3 crash since it was upgraded from 3.99,
which was the last working version. Crashing occurs after the text "Loading
main window" appears in the logo. The current Krita version is 4.1.0-79.1
(originated from
http://download.opensuse.org/repositories/KDE:/Extra/openSUSE_Leap_42.3/)

Here is the console output when Krita started from the Konsole:

spo@linux-c18p:~> krita
