not working properly with kubuntu 14.04

[simon]

running kubutu 14.04 with manually installed and updated kernels (3.15.7 as latest). this tool messes up with your grub.cfg, fails to lead the current grub.cfg and saves the new one just as grub.cfg.new instead of updating the current one.
it fails to create sub-menu entries, these are written in the grub.cfg but not applied and instead the whole entry including the submenu wont show anymore on boot. this is buggy and dangerous.
i managed to manually edit my grub.cfg and i use now the kde integrated grub2 tool instead.
