[gst-devel] review for event handling patch

quick followup - I also tried

gst_element_found_tags(GST_ELEMENT(bin), taglist);

as an alternative for sending an tag event. Anyway that seems to do
roughly the same. In my case does not work :(
Is it suppose to work like this? Otherwise we might want to emit a
warning "can't send tags to a bin".
