------- Comment #11 from Torsten Schoenfeld  2009-03-28 11:38 UTC -------
OK, I can reproduce now.  This appears to be a timing-related threading issue
inside the playbin element.  I attach Quentin's Perl test case, stripped down
to the minimum, and an equivalent C program showing the same behavior.  Leaving
STOP_TIMEOUT set to 100 causes the errors to appear, changing it to, say, 500
makes them go away.

The backtrace in comment 10 contains the relevant information.  Running either
program under valgrind doesn't produce useful information because valgrind's
overhead prevents the errors from occurring.
