This is currently only affecting one user in Jetpack iOS 24.2.

Assigning this a Medium priority since it's a crash (high severity) that's affecting a very low number of users (low impact).

I'm not sure why this happened in 24.2, seeing that the stack trace points to code that has been left untouched for a while. We could probably prevent the crash by ensuring that the index path exists in the table view before telling it to scroll.
