Application: systemsettings (1.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)

-- Information about the crash:
This crash occurred when I tried to create keyboard shortcuts that use the Hyper modifier key.
This modifier is assigned to the caps key using the following xmodmap script:

andrew@o:~$ cat .Xmodmap
remove lock = Caps_Lock
keycode 66 = Hyper_L
remove mod4 = Hyper_L
add mod3 = Hyper_L

(On many computers, the third line is extraneous.) The script is loaded automatically on startup, resulting in

andrew@o:~$ xmodmap
xmodmap:  up to 3 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock      
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Alt_R (0x6c),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3        Hyper_L (0x42),  Hyper_L (0xcf)
mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)

This setup works with emacs and other programs with no problem.  But when I try to configure keyboard shortcuts in Kate, or global shortcuts in System Settings, I get garbage as soon as I press the caps key.  It is not recognized as a modifier key.  Hitting the key again in a new assignment results in segmentation fault.

I heavily depend on the hyper key to navigate the computer quickly using the keyboard, since it provides a lot of new space for keyboard shortcuts.  I hope this bug can be resolved quickly, since in all other ways the latest KDE is totally awesome!

Best,
Andrew

The crash can be reproduced every time.
