XnView Software

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.

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

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

[ 71.448696] XnView[2892]: segfault at 0 ip 00007f67bcf686dd sp 00007ffc53332a00 error 4 in libQt5XcbQpa.so.5.9.7[7f67bceb8000+14a000]

I' having the same problem.

I attached an archive with the images that fail to scale.
