fixme:secur32:schan_QueryContextAttributesW Unhandled attribute 0x54 wine: Unhandled page fault on read access to 0x00000000 at address 0x19e7eec (thread 006d), starting debugger...
Perhaps schannel is to blame? Though SECPKG_ATTR_LOCAL_CERT_CONTEXT seems a little funny, I wouldn't expect iTunes to be using client-side certificates.
