Created an attachment (id=409120)
 --> (http://bugzilla.novell.com/attachment.cgi?id=409120)
Test website which can be easily tested using xsp2 in the root folder.

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.13
(KHTML, like Gecko) Chrome/9.0.597.45 Safari/534.13

When trying to override the browser capabilities of the httprequest class, the
following error is thrown:
Duplicate Key "ie6to9" found in /tmp/test/App_Browsers/ie.browser and in file
/opt/mono-2.8/etc/mono/2.0/Browsers/Compat.browser

on ms.net you are still able to override capability settings

Reproducible: Always

Steps to Reproduce:
1. extract the attached example, which provides an App_Browsers/ie.browser,
overriding the default settings of mono.
2. start the example using xsp2 and start localhost:8080/index.aspx
3. You see the exception in the response.
Actual Results:  
Server Error in '/' Application

Duplicate Key "ie6to9" found in
/home/avkekem/Projects/petrel.git.full/wwwroot/App_Browsers/ie.browser and in
file /opt/mono-2.8/etc/mono/2.0/Browsers/Compat.browser

Description: HTTP 500. Error processing request.

Stack Trace:

System.Web.Configuration.nBrowser.Exception: Duplicate Key "ie6to9" found in

Expected Results:  
the browser capabilities in the App_Browsers should override the default
compat.browser settings provided with mono. (as it works in ms.net)
