Yes I suspect it will break on windows in the case where the user is requested to
choose an icon with KIconDialog and he/she uses the file dialog to select a custom icon
(which will then start with "C:\") -- I think.
I would agree with an #ifdef there, we don't have to suffer for Windows's path braindead-ness :).

Good patch otherwise :-)
