Merge lp:~pitti/ubiquity/only-ubiquity-crashes into lp:ubiquity

[Martin Pitt]

I tested this with deliberately introducing a piece of broken code (None+3) in
the gtk_ui.py constructor. This brings up the "ubiquity has crashed blabla"
dialog just fine now.

Please note that for some reason os.setgid(os.getegid()) and the same for uid
does not work for some reason, so I had to use setres[ug]id().

This also adds an (IMHO missing) sys.exit(1) in the case that apport-gtk is
present. Without this, ubiquity would just continue to run on after an error,
which is a matter of luck at best, and could even be dangerous in the worst
case.

Did you not use misc.drop_all_privileges for a reason? Other than that, it looks fine.

[Martin Pitt (pitti)]

The only reason was my ignorance that it exists :) Works fine, thanks for pointing this out.
