Comment 5 for bug 725408

It looks like this went into ubiquity 2.5.19, which seems to be even worse. With 2.5.18, I can at least deactivate dmraid and lvm volumes, and then the installer will get past that screen without hanging. With 2.5.19, it seems to reactivate them and then hang. Also it now seems to hang while one of the partitions is mounted in /tmp, and leaves it mounted and various partman processes running when I quit the installer.
