SILC server 1.1.2 incompatible with old key files?

[mmiller@hick.org]

While upgrading to 1.1.2 it appears that old key files are not properly
parsed:

16:43:39 silc_pkcs_load_private_key:737: Loading private key file '/usr/local/silc/etc/silcd.prv'

Is this a known issue?  The same file parses correctly with:

SILCd Secure Internet Live Conferencing daemon, version 1.0.4 (base:
SILC Toolkit 1.0.4)

Thanks,
