Yes. It is raised by this line of code:
[NSException raise:NSInvalidArchiveOperationException format:@"Network
error domain:%@ code:%d", [requestError domain], [requestError code]];

It is most certainly NOT occurring on the main thread. Never said it was (in
fact, I figured the bit about NSOperation would imply it was not).
Here's the trace:
