Hi Sebastien,
refering to your request
https://bugs.launchpad.net/ubuntu/+source/yelp/+bug/229668
I'm on Jaunty LiveCD right now, opened Ubuntu Help and typed in the search field 'network'.
First off, the section titles are different from Hardy (there is no section 'mines manual'), so I made a right click on section title 'Synaptic Manual' to find and copy the url of 'gnomine' (which I've mentioned in bug 229668).
Result, yelp closes and requests to send a crash report.
Left click on 'Synaptic Manual' results in loading, but stops after a while and nothing happens.
A left click afterwards on 'Internet and Network' subtitle 'network-manager' results in closing yelp again.
URL behind the title is: file:///usr/share/gnome/help/internet/de/internet.xml#networkmanager

Positive result e.g. left click on 'Add and Remove applications'.
URL behind the title is: file:///usr/share/gnome/help/gnome-app-install/C/gnome-app-install.xml#fdl-section3

I started yelp in the terminal.
This time the right click on 'Synaptic Manual' was positive and I could copy the URL:
file:///usr/share/gnome/help/synaptic/C/synaptic.xml#apparmor-profiles
A left click again results in a crash and a request to send a crash report. Output from terminal:
ubuntu@ubuntu:~$ yelp
I/O error : Is a directory
I/O error : Is a directory
Segmentation fault (core dumped)

Since one is presented to join a bug which is already reported, I didn't know if Apport crash report will be added to bug 229668 automatically, because it didn't appear in the list of known bugs and I attached it there manually.

Attached a screenshot of the window we talk about and the second Apport crash report (after running yelp in the terminal).
