Try the next 0.9.8 snapshot.

The problem was that all cipher string matches were treated as category matches
(strength, algorithm etc) even if the string matched one explicit ciphersuite.

That's fine provided no two distinct ciphersuites have the same
classification.

The problem was triggered by the reclassification of the AES cipher suite
strengths in the latest versions of OpenSSL which resulted in some AES
ciphersuites having identical classifications.
