A setcaps function needs to actually verify the caps carefully. In this case, it was possible to e.g. link a video decoder with YUV+RGB template caps to pngenc. That would cause a crash when the decoder pushes a YUV buffer. Same thing when pushing a valid buffer that exceeds the resolution limits. Also, missing framerate caps field would cause a glib critical warning due to invalid GValue. This fails hard now.
