I created a backup of my Galaxy Nexus with adb backup. The resulting file is named backup.db and it's somehow encrypted.

I wanted to restore the backup, but it stops when it comes to restoring com.android.providers.contacts. I used adb logcat to find out what's going on and found out that com.android.acore crashes during the restore process.

I'd like to gain access to the data in the backup and remove the contacts database to restore everything back to my phone. Are there any other ways restoring the data from the backup?
