SUMMARY


STEPS TO REPRODUCE
1. Open Dolphin
2. Open Configure Dolphin > Interface > Previews, making sure "Folders" is
selected
3. Set "skip previews for remote files above" to "999999 MiB" and Apply
4. Make sure View (menu) > Show Previews is enabled
5. Use Dolphin to browse to local ~/Pictures/ and observe directory thumbnails
(of pictures/videos within those directories) are being shown
6. Use sshfs to mount a SFTP directory with pictures (e.g. `sshfs
user at 192.168.1.234:~/Pictures ~/sshfsmount`)
7. Use dolphin to browse to the mounted sshfs directory. Observe no directory
thumbnail is being shown. Note that individual files' thumbnails are still
shown correctly.
8. Use dolphin to view the same remote directory (by typing in
`sftp://user@192.168.1.234:~/Pictures` in the address bar). Observe the network
mount via dolphin/kio also had individual file thumbnails but did not have
directory thumbnails.
9. Use Nautilus to mount the same network folder, via GVFS. This mounts the
remote directory at /run/user/1000/gvfs/sftp:host=192.168.1.234,user=user. Use
Dolphin to browse to this location. Observe that this also results in only
individual files having thumnails but no directory/folder thumbnail.

OBSERVED RESULT
Folder thumbnails only work on local directories.

EXPECTED RESULT
Folder thumbnails should also work on remotely mounted directories.

Note that all files in the example directory used are under 5MB, and the entire
directory is under 200MB.
