XnView Software

Hi, I've been trying to track down an issue that's been affecting me for a few weeks now, trying to click on a video crashes XnViewMP.

type of video doens't seem to matter, I've tried mp4, webm and mkv and all are affected
I've tried purging my cache and it doesn't seem to matter
autoplay or loop options don't seem to change anything
both flatpak and appimage versions are affected, at least (as those are the only ones I can easily try)
versions from current back to at least 1.88 are affected, which makes me think this may be something in xnview that was affected by a system update, as it was at least playing video up to a month ago or so.
OS: Fedora Kinoite(Silverblue) 42
Other tools (gwenview, smplayer, vlc, etc.) seem to be unaffected.

When I use the flatpak version, it crashes with no error message; the AppImage crashes with the error:

Code: Select all

/tmp/.mount_XnViewGopDMJ/usr/bin//xnviewmp: line 5: 57943 Segmentation fault      (core dumped) "$usr/XnView/XnView" "$@"

Any suggestions/ideas for other things I can try?

please try to start xnview from a terminal to see logs

I did that, but the only useful output when it crashed was the single line that I put in the post above. Here's what seems to be the point when it loads a video to the point where it crashes:

It says it's dumping core but I'm not sure where it's putting the dump, it doesn't seem to be in /tmp or in my home directory.

i've tried on a clean Fedora 42, and no problem to play mp4 files
Please change debug=2 in your xnview.ini
