Bug 303315

The next track shown at the top (right to the currently playing track) is updated too early: Some 2 to 20 seconds before the current track ends, the text is updated to show the track *after* the next one, and the previous track shown is actually the current one. Also, if I enqueue a new track during that period, this is ignored.
This happens for each track, but the time is very different from song to song. I am under the impression that for ogg files, it is much larger than for mp3 files.

Reproducible: Always

Steps to Reproduce:
1. Play a song and wait till shortly before it sends
2.  Observe the "next track" shown by Amarok
3. Optionally, some seconds before the previous song ends, put some title into the queue
Actual Results:  
* Some seconds before the track actually ends, Amarok updates the "next" and "previous" song
* The enqueue request is ignored, i.e. it is enqueue after the next song

Expected Results:  
* The previous and next song should be updated in sync with the current one
* The song I enqueue should be played after the current one

* I am using Debian testing with Amarok version 2.6~beta1+75.g47e75df
* This happens both with the VLC and the GStreamer backend, but the times again depend on which backend I use
* Fade-out is disabled (but it also happens with the default setting)
