Error dialog says to file a bug and has no other info, so, here's a bug. Tried in Developer Edition and Nightly. In both cases it hangs for a while and then fails with the symbolication error.
I dunno if it's the same thing (and sorry your bug sat for so long), but I'm going to dupe this over to bug 1161720 since it should get fixed there anyway.
