commit d40975cbe8ff86fcc4a1b4963fdffc66ddee85ce

    scd: Fix regression for generating RSA keys on card.
    
    * scd/app-openpgp.c (do_genkey): Strip leading zeros for fingerprint
    computation.
    
    --
    
    This bug is difficult to reproduce because the probability is 1/256,
    and key generation takes long time.  The regression was introduced
    when we add the support for ECC.
    
    GnuPG-bug-id: 2150
