Edgy: Evolution: Open link in browser stopped working

[Chanchao]

Before, in Evolution, if there was a link in an email message I could
just click it and it would open in Firefox. 

This doesn't happen for me anymore, is there somewhere to correct that?

Interestingly enough, it DOES work when I click on a link in a
Skype-chat window, of all places.  (I guess Skype is more KDE though, so
perhaps it's a general Gnome setting on what browser to open a link in?)

Cheers,
Chanchao
