Arch Linux

Description:

caja does not show thumbnails for video files on samba shares.

Additional info:

* package version(s)

caja 1.20.2-1

* config and/or log files etc.

I enabled debug for cajas thumbnail code and when I tried browsing a directory over samba containing an MP4 file I got the following dumped to STDOUT:

Steps to reproduce:

Set the 'Show Thumbnails' option to 'Always' and 'Only for files smaller than' to 4GB under Caja's Preferences -> Preview tab. Switch Caja's display to to Icon mode then browse to a samba share containing video files less than 4GB in size.
