This looks like it may actually be a locking problem in directfb.
For the record the internal gdk_enter and leaves are in shared code.
So you should not need them for one port vs the other.
Since the locks differ I think adding them is just changing the timing
ind dfb averting the crash condition.
If Im right you should crash with a plain dfb app using the
window is resized using the combination <win> key><ctrl><mouse movement>.
Try that first.
For the record I've gotten crashes in the past during window movement
with Lite apps.
My suggestion is grab one of the directfb test apps and see if you can indeed
replicate without running gdk.
