Nice work, bugzilla. Failed to past the rest of the comment after the
traceback.

So, after the type_packet, theora proceeds to the decode a buffer, at which
point it renegotiates to 1040x1040 uncropped buffer size, while keeping the
caps the same. videofilter/videoconvert don't like that, and fails to map the
result.
