------- Comment #3 from Wim Taymans  2008-10-24 09:45 UTC -------
The problem was indeed an uninitialized variable in the prepare_output_buffer
function. Your patch however initialized the wrong variable which accidentally
made it work.

        * libs/gst/base/gstbasetransform.c:
        (gst_base_transform_prepare_output_buffer),
        (gst_base_transform_getrange):
        Clear the output buffer variable.
        Cleanups to the error path in the getrange function.
        Fixes #557649.
