Bug#462332: yelp doesn't find some info pages

It shows up as gcc-4.1 there. In fact, when I enter yelp info:gcc-4.1, the 
info page is shown. However, other programs such as GNU info, pinfo or 
khelpcenter seem to do some guessing when they can't find an info page. 
It's probably confusing to see the same thing work in every info browser 
but yelp.
