Comment 1 Kai Uwe Broulik 2021-03-08 19:40:47 UTC

Might have been a KIO/kio-extras version mismatch but I now compiled KIO and kio-extras/thumbnail from master and now kdeinit crashes every time instead in a similar place:

Comment 2 Kai Uwe Broulik 2021-03-16 13:29:45 UTC

Getting constant crashes every time a thumbnail is generated, always in a seemingly different place but always with the memmove
