[Bug 68932] Shuffle + repeat + two-track playlist results in buggy behavior

[Jeff250]

Public bug reported:

Bug: When there are only two tracks in a playlist and both shuffle and
random are enabled, Rhythmbox can have buggy behavior when the next
button is pressed.  If I am playing track A and press next, sometimes
Rhythmbox will highlight track B, replace track A's name at the top with
track B's, but Rhythmbox will play track A again instead.  I suspect
that Rhythmbox's random song chooser allows for the possibility of a
song playing twice in a row, which is fine, but this bug deals with
Rhythmbox visually looking like it's playing one track when it's audibly
playing another.

To reproduce, turn on shuffle and repeat in the options menu.  Then open
a playlist with two tracks (or use the browser to narrow a playlist to
two tracks).  Play a song in that playlist, and then press next until
the bug occurs.  (The bug seems to randomly occur, but it's often enough
that it should occur without too many tries.)
