[0.93.1] [Linux] Segfault error 4 in libQt5XcbQpa

Post by Sjet » Tue Sep 24, 2019 7:48 pm

When I try to start XnView (just the program without loading any image), it segfaults.
dmesg shows:

Code: Select all

Arch Linux, I tried both the normal AUR package and the one using system libs.

So far I have traced this back to a fontconfig issue.
I have to delete the contents of /var/cache/fontconfig before I launch XnView.
If I run sudo fc-cache afterwards, XnView starts segfaulting again.
