This crash wasn't handled at the time, and as this was reported more than six years ago, I don't think there's much chance of making any progress here, so I'm closing this bug report. If you're still seeing similar crashes in modern Emacs versions, please reopen. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
