Import OTR fingerprint from XMPP URI not working

[HolgerMeiners]

I have tried to open a XMPP URI containing a OTR fingerprint w/ ChatSecure. The contact information is correctly imported but the fingerprint seems to be ignore.

xmpp:@?subscribe;otr-fingerprint=<OTR Code>

Basically, I would like to use the fingerprint stored on a NFC tag instead of using the QR code.
