[Evolution] Red Carpet breaks 2/16 snapshot?

[Richard Zach <zach math berkeley edu>]

I just installed Red Carpet 0.9 (on RH 6.2), and since then Evolution 
can't open the mail composer.  I get an error dialog that says "Can't 
open composer window."  (No output on the console.)

As far as I can tell, the only package that came with the 2/16 snapshot 
that was updated is gtkhtml, from 0.8.2-100 to 0.8.3-0_helix_1.

Is this the likely culprit?  Is there an easy fix for this (other than 
downgrading gtkhtml or compiling Evolution from source)?  Or, when will 
new snapshots be available?
