While trying to reproduce bug 819973 I hit a Java exception immediately after startup:

But then the following happened, which is a bit scary:

I didn't manage to connect jimdb to this to get a better trace.

Because this looked quite scary, I modified the current m-c to bomb out in the same place in Java, and lo and behold: same crash, also no possibility to attach jimdb.

Marking this a major because it could potentially be hiding a lot of startup crashes form our stats.

My fault, the crash reporter abort()'s in non-official builds.
