GtkClist, removing the last object.

[Chema Celorio <chema celorio com>]

I found a work arround for the crash that was beeing
caused when removing all the object from a 
GtkCList. The solution was to call :

gtk_clist_clear (list); 

when removing the last object from the list. 
Here is a patch that fixes this problem in gtk+.
There migth be a better way to fix this, since
I am not yet familiar with gtk+ internals, but
non the less, here it goes.


The problem that was causing this bugs seemed to 
be that we where not setting the adjustements to
0 when removing the last object. But clearing the
list seems a cleaner way /me thinks.
