Arg. I just noticed I cut'n'pasted the wrong error message. The error
message above was an old from a different error I made.

This is the error I get:

Gtk-CRITICAL **: file gtkcontainer.c: line 714 (gtk_container_add):
assertion `GTK_IS_WIDGET (widget)' failed.

raised STORAGE_ERROR : stack overflow (or erroneous memory access)

I'm running gvd on the program now and I see that the ptr that the
Some_Widget points to change after the Remove.

Thanks in advance
