Ok.  Does that mean there's no bug filed for the case of apt looking at
recommends on the wrong version of the package?

That's not an accurate characterization of what's happening here.  The error
message shown in the log is from dpkg, not from apt:

 Selecting previously deselected package wine1.2.
 dpkg: regarding .../wine1.2_1.1.42-0ubuntu4_amd64.deb containing wine1.2:
  wine1.2 conflicts with wine (<< 1.2)
   wine (version 1.1.42-0ubuntu4) is present and unpacked but not configured.

So in fact, it's dpkg that's detecting phantom conflicts with
previously-installed versions of packages that have since been removed. 
I've updated the bug report accordingly.

I suspect that bug has since been fixed, as I haven't heard anything about
this kind of failure recently.
