Hi Josh, Yes, I am getting a stack trace as you mentioned. However analyzing the stacktrace doesn't show any call to overrideMimeType() which resulted in the crash. I have attached the stack trace with this email for your reference. I am getting a similar stack trace for the other crashing test too (overridemimetype-unsent-state-force-shiftjis.htm).
You can view the code changes at https://github.com/jitendra29/servo/commit/44ad6b8a666d15e8458b14f78936789de823ed10 We are now working on incorporating the suggested code changes from the review on the recent pull request.
