If somebody thinks he's lying but is accidentally telling the truth, do you consider it lying?

By accidentally I mean that he's passing information that he thinks is false but unbeknownst to him it's actually true.

Lying isn't about the truth value of the proposition, rather about an intention to deceive. If another person is trying to deceive you by telling something that is unknowingly true, s/he's still lying considering his/her bad faith.
