Comment 6 for bug 220142

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 8.4.1.6 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.
