           Summary: playbin2 test7.c fails after two songs

Gapless support with playbin2 is beautiful, when it works. Unfortunately, I've
never been able to get it to work consistently.

I split a flac into many 3-second wav files, and then compiled test7 against
both 0.10.21 and CVS, after adding the line 

  gst_debug_set_default_threshold(GST_LEVEL_INFO);

to get some extra insight. Even with the logs, though, I haven't been able to
find the source of the problem: the first song transitions gaplessly into the
second, but the second song simply stops at the end, emitting no signals.  In
addition, the same problem occurs with wavs, flacs, and mp3s.

I used test7 after both a quodlibet output plugin and a test program written in
Python failed in nearly the exact same fashion.  The problem doesn't seem to be
related to the output plugin, as it happens over both alsa and jack.  The
problem is also apparently unrelated to the about_to_finish signal, as manually
reloading the URI at the right time produces the same results.

I have the output from the runs of test7.c; if attaching them will help, or if
there's any other testing I can do, let me know.
