At least as hard as searching for messages with no subjects.  I don't 
know of a foolproof way to do this, but one way that approximates 
finding unmatched braces is to find and highlight all instances of an 
opening brace followed by arbitrary text and then another opening 
brace.  If you have an unmatched brace, chances are this will show up 
as a larger chunk of text than you expect.  (Of course, this isn't 
foolproof, since it also highlights any cases of nested braces.)  So 
it depends a lot on the kind of text you write.

The following regexp will work:


Choose Find, click on the Regular Expression option and then choose 
highlight.  This will highlight all instances as described above. 
You can then go through these to see if they're the source of the 

Maybe others have a better solution.
