ubuntu-desktop didn't upgrade properly (package is now broken)

Did a partial distro upgrade today. During the upgrade, I got an error that said an error occurred while upgrading ubuntu-desktop, and that I should report this as a bug.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
11.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
ubuntu-desktop 1.217

3) What you expected to happen
partial distro upgrade to perform normally

4) What happened instead
error occurred while upgrade ubuntu-desktop package.
