This problem is shown with a script which used to work ok but with 2.7.0 there's a change, has the amarok api has changed somewhere?

- using the random album script of Marcelo Vanzin (version 1.0) which adds a 'Enqueue Random Album' to the tools menu. When I do that a random album is added to the playlist, the number of tracks in the playlist is updated correctly but the length of the playlist is not updated. 

- the error becomes more marked if you then remove the album  you just added (using amarok basic functionality) when the length of playlist can become rather short (I had 21 tracks with a total length of 6 minutes with one track of 26 mins) - the problem is in the previous point this just illustrates the consequences.


Reproducible: Always
