[g-a-devel]Another at-poke change

["Padraig O'Briain" <Padraig Obriain Sun COM>]

Thie attached patch fixes the crasher bug reported in bug 94849.

When a node is unreffed because its parent was collapsed there are problems if 
we call mnode_destroy(). The value node->data will be pointing to unallocated 
memory. If we set it to NULL then when the parent is expanded we do not have the 
value of the Accessible in the node. Omitting the call to mnode_destroy() at 
this point seems to fix all these problem.

OK to commit?
