Description of problem: Pressing the 'Help'-button in gnome-default-applications-properties brings up yelp with an helpfile explaining how to set you preferred applications. So far so good. But it also speaks of setting "Text Editor Preferences". Which isn't available in the program Version-Release number of selected component (if applicable): control-center-2.16.0-5.fc6
The Text Editor prefs aren't used with the new mime system, but the docs were'nt updated. The upstream bug for this is http://bugzilla.gnome.org/show_bug.cgi?id=352870 We need the GNOME docs team to look into this, as we won't be able to update all the languages ourselves.
