This is not a multiarch host yet.

I cannot see any Breaks of at-spi2-core.

Note that with the command line, I get

The following packages will be upgraded: 
  gtk-update-icon-cache libgtk-3-bin{b} libgtk-3-common 
The following packages are RECOMMENDED but will NOT be installed:

(Note: an upgrade to experimental is bad. BTW, no experimental
packages are currently installed.)

5)     libgtk-3-0t64 recommends libgtk-3-bin               

and then this is worse and worse. If I type 'y' for this solution,
I get:

The following NEW packages will be installed:
  libatk-bridge2.0-0t64{a} libatk1.0-0t64{a} libatspi2.0-0t64{a} 
The following packages will be REMOVED:
  at-spi2-core{u} libatk-bridge2.0-0{a} libatk1.0-0{a} libatspi2.0-0{a} libgtk-3-bin{u} 
The following packages will be upgraded:
  gtk-update-icon-cache 

Similarly, at-spi2-core gets removed without any warning on
the Recommends.
