Proposed patch

Confirming in SVN revision 748424.

The problem seems to be that inside KateFoldingTree::toggleRegionVisibility(),
invalid nodes are deleted. This will also delete the node's children. However,
any (now deleted) children of the node may still be in the list as dangling
pointers. Solution: Delayed deletion of these nodes. It would be nice, if
somebody else could take another look at this, though.
