You need to take a look at the file that was being passed to parse.  One 
way to do this is to set options(error=recover) before running whatever 
led to this.  When the error occurs, you'll see a stack trace, and you 
can try to get the file.  If it's a real file, then things are easy: 
just see why the brace on line 621 doesn't match anything.  But since 
the message doesn't give a name, it's probably something else:  a pipe, 
or textConnection, or whatever.
