 Oops.  Looks like I just didn't wait long enough.  The same problem is
 still occurring:
 
 (gdb) run

 Again, the filter that's causing trouble is this one:
 
 
         <filter type="or" name="non-mp3" visible="t">
                 <phrase negate="t" match_type="regex"
 key_type="subject" case_sensitive="f" key="\.[Mm][Pp]3"/>
         </filter>
