Version:           4.5 (using KDE 4.5.2) 
OS:                Linux

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

    ssh://usuer@server

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://usuer@server form) and passwords and now
I can't click to open :-(.

Reproducible: Always

Steps to Reproduce:
1. Install KeePassX or any other app than can store URL in custom forms
2. Create an entry with an URL like ssh://user@server
3. Doble-click over URL column

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

Expected Results:  
A Konsole is open an a SSH conection is established.

I *think* this bug can be related to SVN commit 1184941 (http://osdir.com/ml/kde-commits/2010-10/msg03648.html) but I'm not a developer so I'm not sure.

I'm using Fedora 13 with kde-testing repo enabled. As I've noted, with KDE 4.5.1 from the same repo ktelnetservice is working as expected.
