Infinite loop: removing page

[Ethran]

on page switch, the app entered infinite loop:

15:06:01.285 PageDataManager          E  Removing current page!
15:06:01.286 PageDataManager          D  Removing page 938ec215-6eec-4e20-817f-7c4116193880
15:06:01.286 PageDataManager          E  Removing current page!
15:06:01.287 PageDataManager          D  Removing page 938ec215-6eec-4e20-817f-7c4116193880
15:06:01.287 PageDataManager          E  Removing current page!

And froze.
