Sorry I didn't reply, I wanted to do more tests, but I forgot.
I don't think the backtraces will help, because when it crashes, it is at
random places.

Anyway, I discovered that the errors only happened when the file was specified
with an absolute path, not a relative path.
The crashes are very random, but I managed to reproduced the error messages
below on ubuntu 8.10, fedora 10 and mandriva 2009.0 with the example file from
ubuntu that can be downloaded at :
http://launchpadlibrarian.net/18785858/patas_de_trapo.oga
With this file, specified with an absolute path, I reliably get these errors :

----play 35
-----stop 35
GLib-GObject-WARNING **: invalid unclassed pointer in cast to `GObject' at
bug_changesink.pl line 29.
GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed
at bug_changesink.pl line 29.
-----play 36
-----stop 36
GLib-GObject-WARNING **: invalid uninstantiatable type `<invalid>' in cast to
`GObject' at bug_changesink.pl line 29.
GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed
at bug_changesink.pl line 29.
-----play 37
-----stop 37

Also, there is a big memory usage difference, when run with relative path, the
virtual memory usage, as seen by top, is around 35m, it is around 70m when run
with an absolute path.
Note that, even with the relative path, the memory usage rise, slowly, but
consistently, so there is probably a leak even with a relative path.


When run with valgrind, I get very different numbers depending on if I use an
absolute or a relative path (both stopped with a ctrl-c after ~50 iterations) :
