Thank you for taking the time to report this bug and helping to make Ubuntu better.
Looks like this bug unfortunatly has existed for quite some time. I found bug 484089 a while ago describing the same issue, so I'm marking this as a duplicate. One of the comments seem to suggest it is possible to install the older amd64 package, but I don't know whether that would still work.
