An android 4.4 try to pick a photo using pictureSource.PHOTOLIBRARY or pictureSource.SAVEDPHOTOALBUM and return type destinationType.FILE_URI.
Now android 4.4, when you select the above options, it opens an "open from" dialog that let you choose from new places as "Recent", "Drive", "Images" and "Downloads" (the names might not be the same as I use the device in spanish and translated it).
If you choose any of them, you get an error, AndroidProtocolHandler, unable to open content URL: the url here with a content://com.android.providers format.
I've tested on phonegap 2.9 because this is the version I use, but I suppose it affects all of them. (in fact I use 2.9.1)
