I have seen your comment in bugzilla about the bug of 'The Insert Link
function doesn't work',Maybe you are right :
http://bugzilla.ximian.com/show_bug.cgi?id=53737

This bug bothered me. please help me to have a look at this.

1. What is the performance of bug?
	* when you add a link with protocol like "http://www.google.com"; 	 
every thing works ok
	* if you add a link without protocol just like "www.google.com"
	  the link wonn't work. And, when you right click the link and 
	  select "copy location", you will see that what you copied is 
	  "cid:/www.google.com".

2. Where dose this "cid:/" come from?
	* in mail-format.c:get_cid()
	* in this function, another function  
	  "camel_mime_part_get_content_id" is called to get thecontent   	  id
of the mime part which is being handled. but almose every
	  time, the content id is NULL. so the function generate a
	  string like "cid:@@@%d" and insert it into a hash table.
	* the string "cid:@@@%d" is handled in another function
	  gtkml.c:expand_relative(). in this function, "cid:@@@%d" is
	  passed in as base. the final location of this link if formed
	  by 3 parts. the first part is "cid:", this is from the base.
	  the second part is "/", this is added manually. the third part
	  is the orginal url,like "www.google.com".

3. My questions
	* what is the content id? 
	* what is the base?
	* why the "cid:@@@%d" is treated as base? what is there
	  relationship?
	* what dose your word "mailer problem with base tag
	  and relative links in the message, reassigning" mean?
