Review request for Plasma, Akshay Ratan and Sinny Kumari.


Changes
-------

Now when you click on empty space, media browser will be initialized. However, pressing escape will still directly take you to home screen. You can get the media browser by clicking on the browser button at the top.


Description
-------

At places we assume that there always be a valid browsing backend. In many situations this isn't true, which is exactly what this patch handles.


Diffs (updated)
-----

  mediaelements/mediabrowser/MediaBrowser.qml e7aa109 
  shells/newshell/package/contents/ui/mediacenter.qml d533b60 

Diff: http://git.reviewboard.kde.org/r/111047/diff/


Testing
-------

Tested some scenarios that I could think of. Please test few scenarios and see if this works.
Akshay: I think the new if conditions make previousBackend necessary, please check that your feature still works fine.


Thanks,

Shantanu Tushar
