The original post to the mailing list mentions the ruby open-id library (along with Java and Python libraries) as being vulnerable.

Checking out the code, it looks like the string comparison at the end of the check_message_signature method will leak timing info (uses rb_str_cmp internally?).

Edit: Was wrong about what could leak.
