I fixed the problem for Nico's test case:

   http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080804/006855.html

The problem was that when using --html-diags we didn't have a  
Preprocessor available when constructing HTMLDiagnosticClient, which  
led to all sorts of badness.

Kay: can you confirm that this fixes the issue for you?
