iOS 7 Aviary SDK 2.4.4.2 crash issue

I have used Aviary SDK 2.4.4.2 in iOS 6 . It is running good and the app is in the iTunes . After release of iOS 7 I have tested the same app in my iPod Touch 5g but it is crashing . When I select the image and entered into Aviary View and selected the effects , it is crashing. The exception log is
Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan nan]'
