I customized it quite much after installing and added a theme, but it dosn’t work with the standard theme eihter.
I reinstalled as you wrote with removal of config file, but nothing changed:
[ford@doloris ~]$ gimp --verbose
Parsing '/etc/gimp/2.0/gimprc' for configured language.
Parsing '/home/ford/.config/GIMP/2.10/gimprc' for configured language.
No language property found.

gimp: fatal error: Segmentation fault
At least it outputs the version:
[ford@doloris ~]$ gimp --version
