Version:           2.0 (using KDE 4.4.5) 
OS:                Linux

I tried to make various keyboard-layouts active to my computer (some of them just for testing purposes). My kxkb limited the maximum amount to four.
In comparison: On my older computer, still running KDE 3.5.10 (debian oldstable, i.e. lenny), the kxkb-limit is not reached at 6 keyboard-layouts made available.

Reproducible: Didn't try

Steps to Reproduce:
I didn't try to reproduce it after a reboot, but this is the way I reached where I am (I apologise for the german terms coming up, but there is no other way, just right now):
systemsettings
-->Persönliches [3rd item]-->Land/Region & Sprache [1st item]-->Tastaturlayout [2nd item].

Actual Results:  
The right-facing arrow right of "Available layouts" switches from green to grey after having installed the fourth item in the active-layout-list. There is no way to drag and drop aditional items there, as well.

Expected Results:  
I expected to activate more than four keyboard-layouts.
