Mark,

Thanks for the patch submission.  I'd tried including this before but I 
think I'd come across at least one instance where there was a file: line 
with no extensions directory within it... which causes an endless loop. 
  Anybody else come across this?  I'm going to go through my old notes 
and see if I can find it.

Regards,
John
