[Christopher Townsend <christopher.townsend@xxxxxxxxxxxxx>]

This is a rather old bug and it sure looks like it doesn't occur
anymore.  Since it's been some time since a crash like this has been
reported, it seems it's been fixed some release ago and I'm marking as
such.

If it does still occur, we can reopen this bug report or open a new one.
