I think the problem stems from the fact that this is a 64 bit system and the update notifier is attempting to look for wine1.6-i386, which genuinely will not exist on a 64-bit system (only wine1.6-i386:i386 will -- there is no 64 bit version of this package, but it is depended on in a multiarch way).
Basically the indicator isn't being smart in a multiarch fashion here. But which package is the indicator in?
