Comment 4 for bug 964694

Is this on the livecd or after installing? On the livecd gparted is already preinstalled, so you don't need to install it. If this is post install, then I'm starting to think there is a bug in the installer. I have seen this happen once or twice now with other packages that are installed on the livecd, but removed during installation. After installing, the files are removed, bug dpkg thinks they are still installed. This may be what is happening here: libgtkmm-2.4-1c2a is installed in the livecd, but after installing to the hd, the library files themselves are removed, but dpkg still thinks the package is installed, so when you go to install gparted, it doesn't install the library because it thinks it is already installed, when in fact, it isn't.
