Dear Maintainer,
I was trying the new gnome3 with session-fallback today. I do/did the
following steps and ran into the above error.
a. Make sure that you are in a gnome-sesion-fallback position
b. right click on the menu bar which has Applications and Places and
get the options 'Edit Menus' and 'Help' .
c. Instead of getting help about gnome3 I get the yelp window with the
above error message i.e. :-
the URI ‘ghelp:user-guide?menubar#menubar’ does not point to a valid page.
Search for packages containing this document.
I searched and saw that yelp was installed. Maybe its a bug or
something, please let me know.
Feel free to reassign it if another package is more appropriate for this bug.
Does this happen everytime?
Yes, it happens everytime.
