iOS 7 iPhoto crashes when attempting to edit a photo journal created in iOS 6

Two of my photo journals cause iOS iPhoto to crash if I try to edit them.

Both journals were created in IOS 6; one on my iPad and the other on my iPhone.

Both journals contain more than 20 pages.

Other journals I created in iOS 6 don't cause a problem if I edit them

I can add pages to both journals.

iPhoto crashes when I press the edit button

Does anyone else have this problem?

I'm hoping a future iOS iPhoto update will solve the problem

As a last resort I could re-create the two journals but that's a lot of work
