When you change one of the crop properties (top/bottom/left/right) after the
pipeline has gone to pauze/playing, the videocrop element is not renegotiating
the caps and with the next pad_alloc comming from upstream, basetransform is
still using the same method for allocing the buffer and this can cause a crash
of the pipeline. (if going from proxy-alloc to non-proxy alloc function)
