Problems upgrading ia32-libs in sid: conflicts with ia32-libs-gtk?

Hello everybody,
today when I have tried to do an upgrade of my sid I got the following error:

I had installed some time ago ia32-libs-gtk_7_amd64.deb from Ubuntu to
have Acrobat Reader working without chrooting.

Any suggestion? Should I remove ia32-libs-gtk and then reinstall it to
solve this problem or is this a kind of bug of this version of
ia32-libs?
