It looks like Tabman makes randomly 1 UITableViewCell's separator missing.

Details:

• PageViewController (PageboyViewController) contains only simple UITableViewControllers
• When subclassed with PageboyViewController all cell separators are visible
• Usually only 1 separator is missing. To be more precise, the separator is not missing but its alpha is set to 0.
• Seems to only occur with UITableViewController not a regular UIViewController with a UITableView
