[Evolution] "cannot initialize shell": unintended fix

[Tavis Barr <tavis mahler econ columbia edu>]

I was one of the Myriad RedHat 7.0 users complaining that Evolution 
wouldn't start for me but bailed out with a "cannot initialize shell" 
dialog.

I just installed Nautilus Preview 3 (the first time I've installed 
Nautilus) and now Evolution starts.  (Impressive program.)

So if someone wants to look for dependencies that might be causing the 
error,  you might be able to go through the Nautilus component packages 
and see what package breaks Evolution.  My suspicion is oaf, since 
that was a problem for someone else and is part of Nautilus.  Or, if you 
just want to get it to work, maybe you can do what I did.

Cheers,
