gdb backtrace

I can reproduce this in gdb with the webkit-efl minibrowser (a simple test web
browser). Normally loading the page and reloading goes fine, but if I reloading
fast enough it crashes (sometimes it takes a while, sometimes it just needs two
quick refreshes). The is leads me to think that something in the stack does not
cope with us setting the state to GST_STATE_NULL at some specific point of the
element life cycle.


The backtrace does not look 100% like the one Christophe attached, I'm not sure
if these should be separate bugs: but mine at least looks 'clearer': It crashes
in thread 1 in gst_memory_unmap() because the ffmpeg decoder tries to free some
video frames.
