This has been happening to me for I think the previous 4 versions of Amarok I have. I can reporduce it almost every time, here's how:
1) Go to Podcasts section, expand any podcast with multiple episodes.
2) Download more than one episode. I'll call them "episode A" and "episode B"
3) Double Click "episode A", it should start playing
4) In the Playlist side, right click "episode B", select "Delete Downloaded Episode"
-- "Episode a" will also be deleted.
If it doesn't happen right away, start at step 2, and it should happen.
I noticed that if I go to my music collection and queue tracks, then go back to the podcast section it won't happen. Also if I were to queue or start playing "Episode B" it won't happen.
This is very annoying, as I often have it delete episodes when I have no internet connection.
Thanks for taking a look.
Could you please upgrade to Amarok 2.5 and test again?
I just tried this in Version 2.5.0, still happening
