whats happening? a crash? for the refcount related thing you
might wanna
try http://refdbg.sf.net. You
could also attach your source, so that we can
look at it.

Leaks can be tracked down with 'valgrind'. But that wond't
help for
refcount issues.

Do you unref all elements or just the pipeline? When you add
an element 
to a bin, the bin becomes the owner of said element, so you
must not 
unref the element yourself. If you want to keep a reference
for yourself 
you have to sink the element before adding it to a bin.

 hmm... are you shutting down your pipeline from a signal
callback and
not from a bus message by any chance ? It sems like a
deadlock because
you try to shut down the pipeline from a streaming thread.

  As mentionned before, seeing your code would be much
easier to spot the error.
