[gst-devel] gst_xml_write_file failing with access violation on Windows XP

[Stani Michiels]

Unfortunately this functionality doesn't seem to be available through
the python bindings on Ubuntu (Gutsy/Hardy). On Hardy the gstreamer
version is 0.10.18 Is there a screenshot somewhere on the web to see an
example image? If not Andreas, can you send me such an image privately?
Thanks in advance,
Stani
