[plt-scheme] Problem with Post/Servlets on the PLT Web Server

Hi All,

I'm currently making some forms on MediWiki, using PLT Scheme
(and the webbot.plt package). I noticed the following problem with
the bindings.

If I've got field names with mediawiki namespaces in them, e.g.

   language:english

And I use these as names for input fields of a form, I get the colon
back in the bindings ('language:english as symbol) when I use the GET 
method
for submitting the form. With the POST method however, I get

  'language%3Aenglish

Is this a bug?
