Comment 1 Jonathan Thomas 2010-12-06 19:44:04 UTC 
Do you have any estimate at about what point in the installation that this crash occurred? (Perhaps near the end?)
Comment 2 Jonathan Thomas 2010-12-06 19:45:04 UTC 
Oh, I should have read more carefully. Nevermind. :)
Comment 3 Jonathan Thomas 2010-12-06 20:07:29 UTC 
SVN commit 1204321 by jmthomas:

Make reloading two-staged so that we can both delete things before they become invalid and cause crashes, while at the same time not reloading too early and causing crashes.
