[Mono-list] NullRefException compiling with mcs

I'm getting the following exception when trying to compile a (fairly 
large) set of files using mcs. I'm using 0.28 because that's the last 
stable Debian package, and I can't upgrade to the -cvs versions because 
they conflict with the libapache-mod-mono package.

Is this a known bug that's been fixed since? Is there anything I can do 
in my code to avoid it? Or should I expend some effort to track down 
exactly which file causes it to happen? (I probably can't send my source 
code to the list, but I can send it to someone in private email if it 
will help)
