I'm also getting the error "Can't import contacts" whenever I open contacts while logged into either or all of facebook chat, google talk, or my personal jabber server. This started after running tracker-contorl --hard-reset which I really should not have done... If anyone has any ideas on how to troubleshoot this I'd be greatly appreciative.
