[SFApplication sendEvent] overrides [UIApplication sendEvent:], does some minor SDK-related work, then hands off to the super class method. As sendEvent: is the entry point for all UI-related activities, it's understandably going to catch a lot of errors whose root causes lie downstream of it.

That's the case here as well. It looks like you need to look at your view controller transitions and try to understand where there might be race condition there, or accessing a controller that's being deallocated, etc.

This is not a Mobile SDK issue.

Ok, I appreciate the feedback.
