You don't give any idnication of how old that snapshot is. Som eof the
emacs-snapshot packages I've seen are very old - in fact, I saw a ubuntu
one today that had a date in 2007!!!

At various times, I've seen similar things to what you appear to be
describing. In my case, it has been fixed with re-fontifying the buffer
using 

M-x font-lock-fontify-buffer

What you are observing are probably intermidiate bugs in the
code. Remember, emacs-snapshot is a snapshot of the CVS development tree
and you can expect to encounter things like this. 

Use M-x emacs-version and find out when the package you are using was
created. If its older than a few weeks, find a newer version or build
from sources. Its likely the problem has been fixed in later versions
(though its just as likely it could come back - thats the downside of
using development code).
