Expected behaviour

No crash.

Other information
In a folder of 113 mobile phone created mp4 files 16 of them routinely crash the thumbnailer. All are very short in duration, but there are a couple of short duration vidoes that thumbnail OK.

I solve this annoying problem
deleting the file xplayer.thumbnailer from the folder /usr/share/thumbnailers
and after this install totem
sudo apt install totem*
Curiously, with Totem installed, the thumbnails have worked again.

Rafam I tried your procedure but no success

[RafaMartorell]

You have performed the action of:
rm -Rf ~/.cache/thumbnails

[Harry-W-Haines-III]

Referencing RafaMartorell's comments. After you delete /usr/share/thumbnailers/xplayer.thumbnailer, if you have ffmpegthumbnailer installed, you don't have to do anything. Just keep using xplayer. I wonder if there is an error in that file that triggers the crash. I have tested this in LM 20 Cinnamon and LMDE 4. Works around the issue and xplayer works fine without it.
