>Environment:
SunOS 5.5.1 Generic_103640-14 sun4u sparc SUNW,Ultra-1
gcc version 2.7.2.2
>Description:
If you've got a filename, with two substrings that qualify as extensions,
and one of them is bound to a handler and one of them is bound to a content-type
(map files and gifs, for instance), you'll end up with both the handler and
the content-type set.  Since the handler takes precedence, this'll sometimes
do what you want and sometimes not.  My problem case was a GIF named 
assu.map.gif that'd end up getting handled by mod_imap.

>How-To-Repeat:
with mod_imap in your server, handling files with the ".map" ext, 
name a gif "something.map.gif" then grab it, it'll be a broken
image because the map handler's trying to deliver it
>Fix:
Don't know if it's the best way, but I reset the handler
back to orighandler if the content-type gets set or
changed based a string later in the filename:

          if ((type = table_get(conf->forced_types, ext))
              || (type = table_get(hash_buckets[hash(*ext)], ext))) {
              r->content_type = type;
+           r->handler = orighandler;
              found = 1;
          }
