Bug in gtk_box_remove.

[johannes nada kth se (Johannes Keukelaar)]

Hi all,

Here's a patch for gtkbox.c. In gtk_box_remove, the removed widget is referred 
to after it's been unparent'ed. However, it may not exist anymore then. (In 
fact, in my program it didn't. However, the bug did not cause a crash until I 
started using ccmalloc, which (among many other useful things) fills free'd 
memory with fencepost values, so that dereferencing pointers in it causes a 
crash.)

P.S. I'll also upload things to the ftp site.
