Hi Rolf,

I have a Bindings project that exports an Objective-C library written by one of 
my suppliers. I don't use it myself directly, but I presume they do?

It just happened when my QA guy was here testing. Not something I've been able 
to reproduce though.

Do you use external accessory yourself? Or through some sort of third-party 
library?

The ExternalAccessory framework is part of iOS, so I would not look for a bug 
there first.

Is this something you can reproduce or did it just happen for one of your users?

It crashed inside ExternalAccessory. That's pretty much all I can say for 
certain.

Speculating a bit my guess would be that the object listening for notifications 
from NSNotificationCenter was freed (have in mind that NSNotificationCenter 
does not ref any objects/notifications, you have to make sure those aren't 
freed yourself).
