I think that commit b946d4639e fixes this crash. It's nice of you to ask the day after the repair. :) I had spent a lot of time trying to replicate that crash, with no success, but yesterday was my lucky day. Claire ran a pessimization experiment on the bytecode compiler that made "image.scrbl" crash reliably. I can't say for certain that the bug that I fixed caused this crash, but the details are a close match for the test content and crash reports.
The bug was introduced in 2009 (commit bc47db42e4).
