This is worksforme, using:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.4pre) Gecko/20070427 BonEcho/2.0.0.4pre

Could you give a talkback ID of the crash?

Attachment: testcase

Ok, I finally was able to get a testcase that crashes on branch. It doesn't crash on trunk.
The testcase uses enhanced privileges, so you need to download it to your computer.

I don't get a backtrace in a debug build from the crash, fwiw.

Given that Martijn said "it doesn't crash on trunk" a year and a half ago, I'm guessing this doesn't affect any active branches now.
