I wanted to add a podcast channel to the playlist by using the context menu -> Add to playlist. This adds ALL the podcast channels multiple times, so isntead of having roughly 15 episodes I ended up with 80'000 tracks. The total amount of episodes in all subscriptions I currently have is about 350... The same problem happens with the "Add to playlist" function in the pop-Up-Dropper. Adding the same channel by drag and drop works fine.
Ralf, this is caused by your recent cleanups of Playlist, Podcast and Collection views, models and delegates, especially the removal of weird static actions handling. Please have a look at this. Note that this is reproducible also in Saved Playlists, not just podcasts.
Let's make bug 318782 the master one for this problem. *** This bug has been marked as a duplicate of bug 318782 ***
