nautilus 3.38.1 fails to generate thumbnails on samba shares
Affected version
- Nightly flatpak: Yes
- Other: Ubuntu 20.04, 20.10 - currently running 3.38.1-1ubuntu1
Steps to reproduce
- open a smb:// URL on the local network in nautilus
- see no thumbnails for videos or images
- see a ton of 1x1px PNGs in
${HOME}/.cache/thumbnails/fail/gnome-thumbnail-factory
Current behavior
No thumbnails are generated for content on samba network mounts even if preferences tell it to thumbnail "all" media, not just local media.
Expected behavior
files on samba shares get thumbnailed correctly.
Additional information
no additional information is printed to journalctl
to indicate why the generation is failing. local generation works fine, as does generation for more nebulous sources, like Google Drive.
this is being filed upstream after filing an Ubuntu specific bug here: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1896138
may be related to nautilus bug #1237 (closed), but it's unclear, since that user has no thumbnail generation whatsoever.
