--- Comment #7 from Edward Hervey <bilboed at bilboed.com> ---
This is definitely an issue in the probe handlers. The contents of the pad
probe data *can* be replaced but can only be unreferenced (which happens when
doing gst_event_make_writable()) if we return GST_PAD_PROBE_HANDLED.

So either we use qdata, or we don't remove the reference (and instead blindly
copy it).

Marking this as a blocker, the issue is also in 1.14.
