Comment 7 for bug 334593

I can confirm that yelp can't access to documentation other than of gnome, for example if you perform a search and then yelp shows search results from docs that are not gnome specific (i.e. I installed the Debian mantainer's manual) and if you intend to access to any of the links that yelp shows it will show an error "the file can't be read, maybe the file is missing or you don't have permission to read it" despite I can browse through nautilus to the folder where it is (/usr/share/doc/....../index.html). It happens with many other documentation, not only with that manual, for example:
file:///usr/share/doc/nano/faq.html#
file:///usr/share/doc/libglib2.0-doc/glib/index.html#
etc, to reproduce, make a search like with a word like "debian" and make click in some content not gnome specific.
After clicking in links that give the error yelp finally closes.
