This sounds like something a bug needs to be filed on.
If you have openssl, can you do:
openssl s_client -connect 192.168.168.132 -showcerts

My instant thought is that there might be an IP address in a
subjectAltName entry of type dNSName, or an IP in the Common Name
I am pasting a post I made on June 7th in the mozilla.support.firefox

a bit at the end...
