Link loading never completes after following link, Abort

[Kiri]

Binary package hint: yelp

After following/clicking a link in gnome-help, the viewer window attempts to load forever.
The window is still graphically responsive.
I was able to select 'Copy link' and then load the link in FireFox, which was already running.
FireFox was able to load the URL.
file://///usr/share/gnome/help/gnome-access-guide/C/gnome-access-guide.xml?_auto-gen-id-13
Subsequently clicking on the home icon crashed.

I have repeated/reproduced crashing the gnome-help which, when loaded from the console, outputs:
Yelp:ERROR:yelp-document.c:275:yelp_document_cancel_page: assertion failed: (document != NULL && YELP_IS_DOCUMENT (document))

Following various other links in Gnome Help worked fine.

The page viewed was.
Orca: Screen Reader and Magnifier
then followed link

DistroRelease: Ubuntu 10.04

LAST TESTED WITH: yelp 2.29.5-0ubuuntu3.

Confirming and marking triaged. Opened upstream https://bugzilla.gnome.org/show_bug.cgi?id=612637 for this. I could reproduce it byt starting yelp, searching for "rhythmbox", and clicking on the "Update Manager Manual" link shown.
