But nothing in wheezy ensured an upgrade from gdm to gdm3. A
transitional dummy package would have helped.

The actual error showed up doing an upgrade test of the xfswitch-plugin
package, which in wheezy carries
  Depends: gdm | gdm3
so it was sufficient to just keep squeeze's gdm package installed during
the upgrade to wheezy, causing the problems show up now where it switched to
  Depends: gdm3
which causes the upgrade happening now after the conflict is gone.

Adding a Conflicts: gdm to xfswitch-plugin probably won't help since it
won't ensure a specific upgrade/install/remove ordering between gdm and gdm3

... somewhat later ...

OK, there are only less than 40 logfiles mentioning gdm, I'll check in
how many cases gdm survives the upgrade from squeeze to wheezy (or
jessie). A significant fraction is obsolete packages.
