Are you using a recent version? 1.6 or 1.7?

I'd recommend trying a recent version and checking if it still happens. 
If the same bug can be reproduced in those versions, could you please 
file a bug about it? 
https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer

Attaching a sample application to reproduce the issue will make it 
easier for maintainers to fix it.

Thanks!
