RE: resizing tables with widget and unref

Hi folks,

I'm having some problems with this too! I've got a sub window from my main
on which has a global clist in it. When this window is destroyed I want
everything destroyed apart from the clist itself, I think it does that, but
when I try and reopen my window I get this error:

Gtk-CRITICAL **: file gtkcontainer.c: line 715 (gtk_container_add):
assertion `widget->parent == NULL' failed.

So I presume it isn't being removed from its container - if I comment out
the line which adds the clist into the window this error does not happen!

What is so obvious but I am missing it anyway?

PS - I've tried a hundred different things on this bit of code, so it is no
wonder it currently seg faults during the callback....
