A UITableViewCell could be deallocated as soon as its row scrolls out of view. UITableView will reuse cells if you specify a reuse identifier, but I don't believe that the docs actually specify the number of cells that are reused.
I'm assuming that the web view is displayed when the user taps a link in the UITextView. If so, when does the crash occur relative to the appearance of the web view?

I have reviewed the code and checked all the "reload…" message we might send to the table view that could cause the deallocation of its cells but all of those calls are executed from the main thread using [[NSOperationQueue mainQueue] addOperationWithBlock:^{…}] so I'm stumped. Are there any other situations where UITableView cells would be deallocated? The view displays and the view isn't unloaded due to memory warning or any other situation.
