For a reason I don't know my ubuntu doesn't show thumbnails for pdf.
in gconf-editor ->-> /desktop/gnome/thumbnailers:
application@pdf/command = "evince-thumbnailer -s %s %u %o"
application@pdf/enable = "True"
evince-thumbnailer file.pdf out.png works perfectly
What can be wrong??
when I installed gnome3 thumbnails worked but everything else didnt.
when returned to gnome2.3 - no thumbnails.
