Bug 485252

SUMMARY
Hello and thank you for responding to recorder autostart issue (482378). About to add note to that, but, in the meantime, downloaded the krita-5.3.0-prealpha-e4b7b670a5-x86_64.appimage containing the autostart fix, just to briefly check if I needed to add anything further to bug report that might be useful, but unfortunately appimage is segfaulting:

$ ./krita-5.3.0-prealpha-e4b7b670a5-x86_64.appimage

Segmentation fault

STEPS TO REPRODUCE
1. made sure permissions right, and double-clicked on the appimage
2. loading shows for about 4 seconds
3. nothing further happens, so ran the above command in terminal to see any error reporting

OBSERVED RESULT
krita doesn't open ... error shows segfault happening

EXPECTED RESULT
appimages usually run perfectly, so had expected that krita opens
