I'm guessing that the avatar reference being sent via the OnAvatarEnteringParcel event to the AvatarEnteringParcel() method in CombatModule is occasionally null for unknown reasons.  This is the only line outside the existing try/catch statement.

I actually moved this statement inside the try/catch for 0.6.9.rc2 which should squash this bug.  This will be foreported to master soon, possibly with logging to work out whether this is a significant problem or not.

You can download 0.6.9.rc2 from http://opensimulator.org/wiki/Download.  This is a fairly stable release candidate as far as OpenSim goes, so it may well become the proper 0.6.9.
