Latest SID update has removed the close buttons

[Alan Chandler <alan@chandlerfamily.org.uk>]

In the latest SID update, it appears that all the close buttons from my 
windows have disappeared (along with the minimize and maximize button). 
 I am using standard Gnome, so I assume its the metacity window manager 
doing this

Are others experiencing the same issue, and is there something that I 
can do to fix it?
