Address book source sync issues

regular console error log messages coming through on a phantom vcard: one I deleted years ago, but for some reason still appears (and now causes Messages to hang)


heres the log excerpt:

fault15:10:13.414897 -0400AddressBookSourceSync-_handleAddsOrModifies: could not parse vCard in <private>



how do I locate that phantom vcard and eradicate it completely?
