I also had this problem and was able to fix it. I imagine the solution for each person will be different.
Find reverse dependencies: $ apt-cache rdepends ia32-libs
For each of those dependencies, try one by one purging them: For example: $ sudo apt-get purge google-talkplugin
Of course, do due diligence and make sure purging that package is okay. Some of the packages may not even be installed.
Then try re-installing... $ sudo apt-get install ia32-libs
