Comment 2 for bug 803782

Or maybe not :-(. I think my backtrace actually has slightly more information than this one. (I built yelp debugging symbols from source).

Anyway, this really isn't hard to reproduce. So if you know how to make a better backtrace, you should be able to do it yourself.

Just

1) uninstall gnome-user-guide,
2) enable system->preferences->assistive technology,
3) then enable Orca under system->preferences->assistive technology->preferred applications->accessibility->visual,
4) log out & back in again,
5) start "yelp", go view->all, click "orca", click "universal access help". (If it doesn't crash straight away, then click "back", and then click "universal access help" again.
