Hello,

Following exchanges on the forum:
http://www.calculate-linux.org/boards/2/topics/32338

I open this "ticket" for bug :)

Tumbler and ffmpegthumbnailer, present and correctly configured.
Option "show thumbnails" "local files only" is selected in the preferences of Thunar.

Unfortunately, the file preview is done randomly.

This is very annoying, especially for handling large images.

I tried several solutions including:
sudo rm -rf ~ / .thumbnails /
sudo update-mime-database / usr / share / mime
Without results.

Thanks in advance

Sébastien.
