Camera api takes long time to return uri when using Camera.DestinationType.FILE_URI

For some reason there is a slight pause(it's very noticeable, almost seems like app is about to crash) when choosing an image from the photo library when use FILE_URI...if I use NATIVE_URL when I choose a picture there is no such pause.

Here is some code:

captureImage: function(){

var onPhotoFail = function(message)

{ //console.log(message); }

var pictureSource; // picture source
var destinationType; // sets the format of returned value

var onPhotoConfirm = function(buttonIndex){

destinationType = Camera.DestinationType.NATIVE_URI;

switch(buttonIndex)

{ case 1: pictureSource= Camera.PictureSourceType.CAMERA; break; case 2: pictureSource= Camera.PictureSourceType.PHOTOLIBRARY; break; }

if(buttonIndex == 1 || buttonIndex == 2){
navigator.camera.getPicture(Messaging.createFileEntry, onPhotoFail,

{ destinationType: 1, sourceType: pictureSource, mediaType : Camera.MediaType.ALLMEDIA, /* encodingType: Camera.EncodingType.JPEG, */ allowEdit : false, saveToPhotoAlbum: false, quality: 50 }

);
}
}
urapp.notify.confirm('Image Capture','What would you like to do?',["Take Photo","Choose Existing", 'Cancel'],onPhotoConfirm);
},
