If I create a new shortcut, it will not work if the key's name is XF86WWW or XF86Launch1, ... ;
but it will if it's XF86Terminal or XF86Launch0 (for instance)

Reproducible: Always

Steps to Reproduce:
Systemsettings > Shortcuts & Gestures > Custom Shortcut
Edit > New > Global Shortcut > Command/URL
 - Action : kwrite (for the example)
 - Trigger ==> I use a special key (multimedia key) of my keyboard

The name of that key is defined in a xmodmap file (it is mandatory, otherwise it is not recognized at all) :
 => the file ~/.xmodmap.kde contains "keycode 195 = XF86WWW"
 => I run "xmodmap .xmodmap.kde" at KDE startup

Actual Results:  
In the "Trigger" window, the key "WWW" is displayed ==> the key seems recognized ; however, after applying the modification the shortcut doesn't work !

If I try another name for the key (file .xmodmap.kde modified):
=> it will work with 
   -> XF86Terminal
   -> XF86Launch0
   -> XF86Launch3
   -> XF86Launch8
   -> etc...
=> it will NOT work with 
   -> XF86Mail
   -> XF86Launch1
   -> XF86Launch2
   -> XF86Launch5
   -> etc...

Expected Results:  
Should work whatever the key's name !

rem: it's weird that for instance XF86Launch3 works but NOT XF86Launch5 ??? What the difference ??

rem: the key's names that worked or not were different with my previous installation (Fedora 14 instead of 15), although it was also KDE 4.6.3
