probably because the arguments you supply to kprocess are simply
unsuitable for execution without a shell. with a shell all args are
simply concatenated and then word-split and substituted by the shell
(that's why they need to be quoted), while without a shell every
argument is sort of automatically quoted - entering "echo hallo" (with
the quotes) on the command line does not work, either. especially, if
you additionally quote it - then it's something like "'echo hallo'".
