[Mediawiki-l] Session problem with Mac OS X widget

[The Centerfielder]

And now for something completely different. Sean Billig's Wikipedia  
widget for Mac OS X (see http://www.whatsinthehouse.com/widgets/) is  
very cool. I'm trying to modify it to read my own wiki (http:// 
www.dkosopedia.com, which is MediaWiki v 1.5.7), and am having a  
problem.

I can search for an article on my wiki with the modified widget and  
retrieve the article ok, but when I click on an internal link in that  
article (for example [[Washington Post]]) I get an error like the  
following:

   There is no page titled ":Washington Post?dkuser dkosopedia  
session=a5b3e0d963ea0fe29c9f8bc319743992".

where "dkuser" is the name of the account owning the wiki. Clicking  
external links (for example [http://www.cnn.com]) work correctly  
(they open cnn.com in Safari).

Obviously something is adding dkuser_dkosopedia_session to the query  
string and I'm sure there's a very simple explanation, but it's  
beyond me.

A possible clue... Note the ":" first character in the error message.  
Internal links to pages with something in front of the  
":" ([Special:Recentchanges]) DO work ok.
