If this was a Gtk bug, every Gtk and Gnome app would be broken in an
obvious way. So it's 95% likely there is something wrong with your code. 
However, you haven't posted enough code for us to tell what that is (at
least, I don't see it, perhaps someone else will).

How do you know whether list is valid or not in this function? (i.e., when
you say list isn't passed properly, how do you know that?)

Perhaps you accidentally destroy 'list' at some point? Perhaps the 
pointer is invalid when you call gtk_signal_connect?

The part you've posted looks fine, perhaps post a larger code segment.
