Comment 6 for bug 598890

Ok... the problem is here... It very strange that the key vanishes in gconf like that... and somebody else reports me the same problem by mail... :s

For solving your problem you can try those commands :

  → For Debian/Ubuntu :

gconf-schemas --register /usr/share/cover-thumbnailer/cover-thumbnailer.schema

  → For other distros :

export GCONF_CONFIG_SOURCE=`gconftool-2 --get-default-source`
gconftool-2 --makefile-install-rule /usr/share/cover-thumbnailer/cover-thumbnailer.schema

Then you have to logout and login again for cover-thumbnailer starts working.

I'll try to understand why the GConf keys disappear :/
