Try to add additional filters, such as:
+*.zip +*.cgi

This may be because the files are located 'outside' 
(that is, in upper structures, or in other host 
address) - this may be due to javascript tricks, too, 
or robots.txt rules (look at the hts-log.txt file if 
necessary!)

Please report these bugs, if possible :)
(apart from the strange-and-totally-random crash at 
the end of a mirror, and minor interface bugs, the 
engine should be stable - in fact all remaining bugs 
seems to come from the interface - darn!)

(note that you can donate $300 to the FSF 
(www.fsf.org), too :)) )
