AIR SDK 15.0.0.349, Android 5.0 and CameraRoll

Have a couple of problems with the above in some software I'm writing.

1. Images saved to the CameraRoll/Gallery prior to the installation of my software cannot be loaded by it and results in a Error #2032 Stream Error. Images saved afterwards to the CameraRoll/Gallery work fine. I realise this makes no sense, why should the date of installation matter?

2. Images loaded from the CameraRoll in portrait mode into my program are cut off about half way down. Landscape mode works fine.

Neither of these problems are apparent in versions of Android prior to 5.0.

Any help would be gratefully received.
