The code in urllib.quote fails on Unicode input, when
called by robotparser with a Unicode URL.

Traceback (most recent call last):
File "./sitetruth/", line 415, in run
pagetree = self.httpfetch() # fetch page
File "./sitetruth/", line 368, in httpfetch
if not self.owner().checkrobotaccess(self.requestedurl) : # if access disallowed by robots.txt file
File "./sitetruth/", line 446, in checkrobotaccess
return(self.robotcheck.can_fetch(config.kuseragent, url)) # return can fetch
File "/usr/local/lib/python2.5/", line 159, in can_fetch
url = urllib.quote(urlparse.urlparse(urllib.unquote(url))[2]) or "/"
File "/usr/local/lib/python2.5/", line 1197, in quote
res = map(safe_map.__getitem__, s)
KeyError: u'\xe2'

   That bit of code needs some attention.  
- It still assumes ASCII goes up to 255, which hasn't been true in Python for a while now.
- The initialization may not be thread-safe; a table is being initialized on first use.

"robotparser" was trying to check if a URL with a Unicode character in it was allowed.  Note the "KeyError: u'\xe2'"
