xdg-email fails to find kmailservice in kde4 environment

[Yuri]

I have kde4 installed. chrome's way to fulfill mailto: links is to call 
xdg-email. And it fails to find kmailservice:
$ xdg-email xxx at xxx.xxx
/usr/local/bin/xdg-email: kmailservice: not found
test: : bad number
test: : bad number
test: : bad number

The first line is the problem I am talking about, the other three lines 
is some other issue.
kmailserver is in /usr/local/kde4/lib/kde4/libexec/ directory which 
isn't normally in PATH. That's why the problem occurs.

Even though xdg-utils is under the gnome maintenance, it should still 
work with kde4 since some non-gnome programs chose to use it too.

xdg-utils-1.0.2

Thanks,
Yuri
