Comment 9 for bug 1187938

I kind of fixed it by following what Ronan Jouchet wrote. I believe the problem is mainly with conflitting multilib packages, but I really can't say for sure right now. Don't know if it really can help, but:

sudo apt-get install ia32-libs ia32-libs-multiarch
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 ia32-libs-multiarch:i386 : Depends: gtk2-engines:i386 but it is not going to be installed
                            Depends: gtk2-engines-murrine:i386 but it is not going to be installed
                            Depends: gtk2-engines-pixbuf:i386 but it is not going to be installed
                            Depends: gtk2-engines-oxygen:i386 but it is not going to be installed
                            Depends: ibus-gtk:i386 but it is not going to be installed
                            Depends: libcanberra-gtk-module:i386 but it is not going to be installed
                            Depends: libgail-common:i386 but it is not going to be installed
                            Depends: libgtk2.0-0:i386 but it is not going to be installed
                            Depends: librsvg2-common:i386 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

is what I get when I try to install ia32-libs (I need it for teamviewer for example). Hope it helps tracking down the problem.
