    Classification: Platform
           Product: GStreamer

Patch to fix the function passed into the low-level operation.

In Gst.Pad.set_query_function the wrong method is specified when passed to the
underlying C function. Also, in set_query_function_full the udata paramter is
ignored/dropped.

The bug results in failures attempting to call the chain function in
_chain_override and in at least a few cases in segfaults of applications.
