Yup, point 4) fixed (although it doesn't actually belong to this thread since it was a problem with makehuman and not the debs). But it would be better to let the user choose the destination path (the command `zenity --file-selection --file-filter="*.mhm"` displays a GTK dialog on Linux, but maybe there's already something similar built-in on Python).
About the .deb, I think the bug report shows all the issues I said and some other ones I agree
(But it's "makehuman.desktop", not "makehuman.application".)
And the version number (personal opinion): they normally have 3 numbers: generation, version and revision. So 1.0a4 would be generation 1, version 0, revision alpha-4 (you could add something like 1.0a4svn627 for nightly builds, or even just 1.0svn627); 1.0.0 would be the final release, 1.0.3 the 3rd bugfix release, 1.1.0 a new version, etc. I.e. the "alpha-X" replaces the revision number.
