Bug 183518

Version:           2.0.1 (using 4.1.4 (KDE 4.1.4), 4.1.4-2.fc10 Fedora)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.12-170.2.5.fc10.i686

The last track of any playlist is not properly scrobbled to last.fm, and ends up not getting stored under the user profile. 

How to reproduce: Set up a playlist of any length in Amarok and play it with the last.fm "plugin" running and properly configured. Then, open the user last.fm profile in a web browser and monitor the submission of the tracks.

Expected behaviour: As soon as a track is loaded, it should be displayed as "Listening Now" under the "Recently Listened Tracks" list. When the track finishes, it should be permanently stored at the list.

Observed behaviour: Scrobbling of all tracks but the very last one works fine. The last track gets shown at "Recently Listened Tracks" as "Listening Now" while it is playing. Once it and the playlist end, however, it vanishes from "Recently Listened Tracks" instead of staying there.

Additional info: It was mentioned (at some last.fm support forum if I remember correctly) that this issue could be caused by Amarok not submitting the "track end" signal to last.fm for the last track. That does seem to be the case, judging from the following console logs, obtained after playing two tracks in a playlist (the first one got scrobbled correctly, the second one not):

Note that data is sent to last.fm ("HTTP POST...") after the first track ends (messages "Argument missing: Amarok - No track playing., 0:00"), but there is nothing like it after the second track ends.
