I had a crash in 5.1b SR-2. I'd been using Logos, and been notified on an update. I clicked the link in the yellow bar to restart, and it crashed whilst trying to generate the layout thumbnail. I didn't have logging turned on, so this extract from the crash log is as good as you're going to get, I'm sorry.
