CTree "tree-expand" signal

[faboo <eca xpres net>]

I've been having this very odd problem for a while now: I've got a GtkCTree, 
'folders', and when the user opens a node (expands that branch) I need to do 
some work. Now, I have a function connected to the "tree-expand" signal, 
who's declaration looks like this:

void foldersCTreeTreeExpand(GtkCTree *folders, GList *nodeList, gpointer
        object);

Getting the signal and such goes just fine. Problems arise, however, when I 
try to use 'nodeList' argument, which should be a pointer to the GList inside 
of the just expanded GtkCTreeNode structure. If I convert 'nodeList' to a 
GtkCTreeNode using the GTK_CTREE_NODE() macro, and then try and use the 
results as a parameter to a function function, the results range from 
incorrect data, to a segmentation fault and a program crash.
Is there something I'm missing about the 'GList *nodeList' parameter of this 
signal and there is some other way I need to extract its corresponding 
GtkCTreeNode? 

I'm using gtk inside of a C++ environment (using gcc/g++), and I thought that 
might cause some issues (as the GList * to GtkCTreeNode * conversion is just 
a type cast), but it doesn't really seem like that should be the case.

I am very confused.
