Xfce, tumbler, dbus: Thumbnail not inferred from file content (vids)

Dear list,

I also posted this on the Archlinux forum, but without reaction. The subject might be more XFCE than Arch so I thought I'd give it a try here. Since about 4 months now I've had problems with creating thumbnails for video files on a network share (samba). Image thumbnails on this share is no problem and neither is creating local video thumbs. I use Xfce (and therefore tumbler). I can play these videos without problem (tried mplayer and parole). I googled for information about this but found none about this particular issue. After it bothered me enough I decided to reinstall my laptop last week to see if it would solve the problem. The problem however is still there. I started to read about the components involved and suspected it might be a problem in dbus. I discovered and ran the wonderful "dbus-monitor" utility while browsing with thunar to my smb share. In the bus-monitor output I see the following message for each video file (and therefore each file tumbler tries to make a thumbnail for): Thumbnail could not be inferred from file contents. Googling for this I only find references to source-code commits (which is beyond my current comprehension).

• I have set the option in thunar to always create thumbnails.

• My server is called berlin, the share rolf (as is clear from the output below).

• In this session I access a shared folder with 12 older Ali G episodes in different video formats.

• When I copy the files to my local drive the thumbnails are created without problem.

I have the following (relevant?) packages installed:

1. thunar 1.6.2-1

2. ffmpegthumbnailer

3. dbus 1.6.8-6

4. dbus-glib 0.100.2-1

5. gstreamer 1.0.5-1

6. gstreamer0.10 0.10.36-1

7. gstreamer0.10-bad 0.10.23-3

8. gstreamer0.10-bad-plugins 0.10.23-3

9. gstreamer0.10-base 0.10.36-1

10. gstreamer0.10-base-plugins 0.10.36-1

11. gstreamer0.10-ffmpeg 0.10.13-1

12. gstreamer0.10-good 0.10.31-1

13. gstreamer0.10-good-plugins 0.10.31-1

14. gstreamer0.10-python 0.10.22-1

15. gstreamer0.10-ugly 0.10.19-5

16. gstreamer0.10-ugly-plugins 0.10.19-5

17. ffmpeg 1:1.1.3-1

18. ffmpegthumbnailer 2.0.8-2

19. gstreamer0.10-ffmpeg 0.10.13-1

Hope someone can give me some triggers as to how further investigate this problem. Does anybody else have this problem?

Regards,
Rolf Deenen

Here is the complete dbus-monitor output (I cut it of after the first 3 errors. These are repeated for all files): It seems to "see" the files, and recognize their filetype.
