Can't open URLs like ssh://usuario at servidor

[Christian González]

(Using Fedora 13 i386 + kde-testing + kde-unstable.)

With KDE SC 4.5.1, when I try to open an URL like this:

     ssh://usuario@servidor

a Konsole appears and a ssh conection is established. Now I've updated
to 4.5.2 and this message appears:

     Error - KIOExec
     Could not start process Unable to create io-slave:
     klauncher said: Error al cargar «ktelnetservice %u».

This is very uncomfortable since I use KeePassx to store all my
server's URLs (in ssh://usuario@servidor format) and passwords and now
I can't click to open :-(.

Is this a known bug? Is it related to
