Konqueror redirects to microsoft.com when visiting a website with an embedded WMV video.

Steps to reproduce:
1) Uninstall any media player plugins for the browser, (e.g. totem-mozilla) and mozplugger.
2) Start Konqueror and browse to http://www.snapkeys.com/en/imaginaryinterface/letters
3) Konqueror shows a pop-up box saying: "Missing plugin - Konqueror. No plugin found for 'Microsoft Media Format'. Do you want to download one from http://www.microsoft.com? [Download] [Do Not Download]".
4) Click the download button. A new window opens on the URL http://windows.microsoft.com/en-US/windows/windows-media-player. That web page offers to download Windows Media Player, which is non-free software.

Expected: the pop-up box in step 3 should suggest installing a free media player/plugin. Alternatively it could be not shown at all.

Attached is a patch from Parabola GNU/Linux that implements the latter.
