No password prompt for importing otr keys

[Finn10111]

I am using ChatSecure 13.1.3-beta-4 on Android 2.3.7. I used keysync to generate the otr_keystore.ofaces file and placed it into the root directory of my sd card. After trying to import the keystore, ChatSecure ask to scan the QR code and wants me to install the Barcode Scanner via F-Droid. Unfortunately the Barcode Scanner isn't available for Android 2.3 anymore so I am not able to import the keystore.

The expecteded behaviour is that ChatSecure asks for the password the keysync tool gave me.
