Decryption problem with ODK Briefcase

I'd be happy if someone could help me with this.

I am experimenting with encrypted forms. First, I confirm that the form works just fine unencrypted, and then I add a public key to it. ODK collect collects the form just fine and uploads it to the Aggregate server.

I can download the forms using Briefcase and confirm that unencrypted forms export just fine. However, when I try to export an encrypted form, I get the following error:

Starting Export...

I have installed the unrestricted Java Cryptography jars.

The submission.xml file looks correctly formed to me. I am attaching it in case anyone else can see a problem.

I'm using ODK Briefcase v1.3.2 Production under JRE 1.7.0_25, 64 bit under Windows 7 (64 bit).
