browser wrapper

Hi,

we have simple appwrappers supplied with gworkspace.

The infoplist contains
   XAppWrapper = YES;

and this works for opening file in applications. There are side-effects 
with GWorkspace, but it mostly works in the sense that things open. If 
the app is reasonable, it will also open more files.

I would like to  have this simple functionality also for Web Browsers.
There are already a couple of wrappers for browsers: firefox, seamonkey, 
konqueror, iceweasel...

Now they don's seem to work. I think is becuase they do not register 
CFBundleURLTypes

So I thought to add to the seamonkey wrapper:
   CFBundleURLTypes = (
     {
       CFBundleURLName = "Web site URL";
       CFBundleURLSchemes = (
     http,
     https
       );
     }
   );

but it doesn't work. The wrapped app is seen in systempreferences 
internet panel and I can select it. However, if I click on an URL this 
do not work as expected.

Seamonkey opens or comes to front, nothing happens.
The calling app (e.g. GNUMail with a link) hangs and complains after a 
while with No service matching 'OpenURL'
firefox comes and may open the link (or maybe not)
