*** Bug 185794 has been marked as a duplicate of this bug. ***
This issue is on Red Hat Engineering's list of planned work items for the upcoming Red Hat Enterprise Linux 4.4 release. Engineering resources have been assigned and barring unforeseen circumstances, Red Hat intends to include this item in the 4.4 release.
Fixed upstream, I think that's all that is needed for this ICE on invalid.
