NullPointer exception in Cordoba 3.5.

Question

I recently updated the application for cordova from version 2.9 to version 3.5. I added the necessary plugins via the command line and made a cordless build of my application. I get a Nullpointer exception when reading / writing a file through a plugin. The following is a stack trace:
