Spotify stops playing album at end of track - daemon tries to relogin

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Triode Spotify plugin and connect to Spotify account
2. Play album URL: spotify:album:2u0soOazLhDgesYccvVscn (Wagnre - Siegfried)
3. Wait for third track

What is the expected output?

Music.

What do you see instead?

Nothing.  Players all say they are playing but progress is stuck at end of 
second track.  The spotify log file says that it tried to relogin at precisely 
the point that the system stopped playing:

[12-08-17 10:46:35.6481] Plugins::Spotify::Spotifyd::relogin (211) requesting 
relogin

(This happens every time.)

What version of the product are you using? On what operating system?

LMS is ARM (squeezeplug) with "7.7.3 - r33949".  Triode is latest.

Please provide any additional information below.

I can play some other albums fine, and some have the same problem.

I don't think the relogin is correlated.  Tried a few more times and with 
different albums and the squeezebox server logs don't show anything fishy.  The 
spotify helper logs look like this (it stopped at 11.15):
