File.getDirectoryListing() and browseForOpen() no longer working in Android OS 4.4.2

Hi,

As of Android 4.4.2 ( aka. API 19 - Kit Kat ), it appears that File.userDirectory.getDirectoryListing() is no longer returning anything.  Also, a call to File.userDirectory.browseForOpen() causes my app to crash instantly.

Both functions work fine in Android 4.3 ( aka. API 18 - Jelly Bean ), however.

Did something change, or are new permissions required for using the File API, in 4.4.2?

My setup:  I am testing in AVD ( Android Virtual Device ).  My app is compiled with AIR SDK 14.0.0.178 ( note: the app crashes on load if compiled with AIR 15.0.0.249, but that's due to a different problem ).
