That's because this symbol does not exist, It just came from the defs
snippet I sent ;) The problem is, the type above it not a GType, so
various things are missing to properly support it.

Google just found this:

http://www.daa.com.au/pipermail/pygtk/2007-November/014433.html

You can try one of the two approaches described there. Note that I
can't help much here, I've never done such a thing.

Agreed, and even if they did, that changes would not appear in
Fremantle at this stage :/

I don't think there is such "define-struct" ... I only see usage of
define-object. I take most examples from pygtk, but there I haven't
find any type that did not have a GType.

Good luck,
