That looks like a null-deref crash.  I wonder what's null...  Olli, could our id flags be off?
Comment 2 Olli Pettay [:smaug] 2012-07-20 12:10:11 PDT
Ah, I guess so
Comment 3 Olli Pettay [:smaug] 2012-07-20 14:52:07 PDT
Created attachment 644485 [details] [diff] [review]

In other places we check the length of ID, and empty ID is no-ID.

If there are still some other similar crashes after this patch landed, 
please file a new bug and CC me.
