Comment 1 Colin Walters 2004-02-05 06:21:27 UTC

Oh, and this doesn't happen with my day-old CVS checkout; perhaps it's
caused by one of those memleak fixes that went in today?

Comment 2 David Schleef 2004-02-05 17:14:57 UTC

I fixed this last night.

        * gst/gstelement.c: (gst_element_clear_pad_caps): Make sure we
have
        a GstRealPad before accessing its structure members.
