Bug Description

Can be reproduced using silo 4 as of today.

How to reproduce:
 * Go to the Tracks department on the My Music scope
 * Press the Play icon on various songs
 * Notice how the dash becomes unresponsivefor around 5 seconds sometimes

Note: may be related or not, but it seems the playlist is not cleared properly since the debug now says
   virtual int AalMediaPlaylistProvider::mediaCount() const
   track_index_lut.size(): 1050
when the playlist has only 10 songs

It might be related to bug #1511313. Does the dash use the same database as music-app ?

Paweł Stołowski (stolowski) wrote :

Dash doesn't use any music database - the scope (backend process) is the one responsible for providing the list of song uris (treated then as playlist by the Dash). The Music scope gets the list of songs from mediascanner database, using mediascanner's API. As discussed on IRC, the list of songs exposed by the scope looks fine, in particular there are no duplicates (http://pastebin.ubuntu.com/12998325/)
