And that's true.

For example, if I use ssh to access a remote machine, which is using KDE:
    ganton@t1:~$ pidof kded4
    12511 1382
those were two results returned.

For more information:
    ganton@t1:~$ ps aux | grep [1]2511
    root 12511 0.0 0.8 79700 5300 ? S Dec06 0:07 kdeinit4: kded4 [kdeinit]
    ganton@t1:~$ ps aux | grep [1]382
    ganton 1382 0.0 7.1 266424 45632 ? Sl Dec06 0:43 kdeinit4: kded4 [kdeinit]
we see that there are two process named "kded4", one for "root" and another for the user "ganton".

But if something like "pgrep -u" is used:
    ganton@t1:~$ pgrep "kded4" -u "$USER"
    1382
there is no "two results returned" problem.

I suggest changing those "pidof" that appear in the code (for example, in the patch).

Thanks for the work!
