i did some additional looking into the issue ... and from my
investigation so far i think the problem lies in the passing of the
function pointer argument to the gst_iterator_fold function call ..

There's a typecast being done for the function pointer argument
(GstIteratorFoldFunction) find_colorbalance_element

and i think it's the missing prototype definition for
GstIteratorFoldFunction that causes the problems here. That prototype
Seems to be declared in /usr/X11R6/include/gst/gstiterator.h 

I tried simply adding #include <gst/gstiterator.h> to the
src/backend/backon-video-widget-gst-0.10.c-file ... but apparently
that's not enough.

Hopefully this will provide some additional information to sort out this
