Bug Description

On 8.04 Release Candidate Yelp window closes silently and .xsession-error contains

Yelp:ERROR:(yelp-document.c:275):yelp_document_cancel_page: assertion failed: (document != NULL && YELP_IS_DOCUMENT (document))

when these steps are followed:

Open yelp window
Go to Advanced Topics
Go to Writing Your Own Programs
Go to Learning how to program

On my machine nothing happens except a spinning-disk pointer. Impatiently select "Learning how to program" again and Poof!

LAST VERSION TESTED: 2.29.5-0ubuntu3 (Lucid)

yelp 2.25.1-0ubuntu2 seems to be afflicted with this bug when clicking on "Connecting to the internet" (Ubuntu help center welcome page) - this is consistently reproducible here. Jaunty, current as of approximately two hours ago.

Can you reproduce with yelp 2.25.1-0ubuntu3? I can't.

Nope this seems fixed with -0ubuntu3.

I think the original bug is still present - you can verify it by going to the keyboard config documentation (gnome-help ghelp:user-guide#goscustperiph-2) and clicking on the Mouse Keys Preferences link. The link doesn't work, and clicking it again after a while leads to this crash.

Maybe the problem only happens on certain links which are somehow broken. The "Learning how to program" mentioned above seems to be fixed now, but apparently there are other such links which cause the crash.

I searched for 'wireless', clicked on a 'Users Administration Tool Manual' link, minutes drifted by, just a default arrow (not spinning wheel) as mouse pointer in most of the window, with a spinning wheel pointer on the window menu bar; window title showed 'Loading...', then I closed down with close Window X button; seemed to close clean.

Restarted help with panel icon, searched again for 'wireless', clicked on 'Internet and Networks' and got the following message:-

The file ‘/usr/share/gnome/help/internet/en_GB/internet.xml’ could not be parsed because one or more of its included files is not a well-formed XML document
