That's really strange, could you send me a file and the pipeline you use 
with gst-launch to play it ?
I would prefer a pipeline using base plugins (ogg vorbis/theora) if you 
are getting crashes with it, as i've already these plugins built in 
debug with vs6...
I'll test in the same condition but with the binaries built with vs6, 
trying to reproduce your crash and debug.
Thanks,
Sebastien
