Thumbnailers are missing in gconf

[Patrick Ulbrich]

In Oneiric thumbnailers are missing in gconf, i.e. all gtk2 apps (e.g. Basenji) that generate thumbnails of media (images, videos...) won't work.

Importing the attached gconf XML from natty ("gconftool-2 --load thumbnailers.xml") will fix the problem.

This bug is really easy to fix, I'd be very happy if the fix will make it into oneiric as it is pretty critical for me.

The bug affects all apps that make use of thist api: http://developer.gnome.org/gnome-desktop/stable/GnomeDesktopThumbnailFactory.html

Images don't seem to be affected, but all other media types.

Here is a snippet (by jtailor) to reproduce the problem:

import gnome.ui
import gnomevfs

path = "test.avi"

uri = gnomevfs.get_uri_from_local_path(path)
mime = gnomevfs.get_mime_type(uri)

thumbFactory = gnome.ui.ThumbnailFactory(gnome.ui.THUMBNAIL_SIZE_LARGE)
if thumbFactory.can_thumbnail(uri ,mime, 0):
    thumbnail = thumbFactory.generate_thumbnail(uri, mime)
    if thumbnail != None:
        thumbFactory.save_thumbnail(thumbnail, uri, 0)

I wrote a little bash script that imports thumbnailers from /usr/share/thumbnailers into gconf in GNOME 3 (see attachment).

Status changed to 'Confirmed' because the bug affects multiple users.

[MestreLion (mestrelion)]

Shouldn't this import be the other way around? AFAIK, Gnome 3 uses /usr/share/thumbnailers/*.thumbnailer files to implement external handlers, NOT gsettings. The gconf2 was the Gnome 2 (ie, Natty and before) way of registering external thumbnailers.

No, this bugreport is about missing thumbnails in gtk2 apps.
