I have solved the problem, but I guess is a little shoddy.
1. Edit your /etc/X11/Xsession and add this line at its begining: export QT_IM_MODULE=simple
2. Restart your X session
The problem was KDE use an incorrect Input Method for the spanish language: xim. Setting the Input Method to the "simple" solve this problem.
IHTH!
