Application: kcmshell4 ()
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.7-desktop i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I changed the keyboard shortcut for "Lock Session" under "Run Command Interface" in "Global Keyboard Shortcuts" to "Meta + L" (which is what appears after I held down the "Fn" key on my laptop keyboard and pressed "F1", which had a lock symbol on it), which is the lock shortcut on Windows. After clicking "OK" and then pressing meta + L (the normal way, not using the Fn key), the crash reporter opened up. A few seconds later, the screen apparently locked, because the password dialog opened up without showing the screensaver, however, pressing "Esc" dismissed that unlock dialog and then showed the screensaver. Incidentally, when I tried to enter my password to unlock it and submit a crash report, the dialog did not appear, thought the screensaver froze, and upon pressing "Enter" after typing my password, the screen unlocked (this particular problem has happening for quite a long time).

I am not sure whether the crash occurred from changing the key combination from "Ctrl + Alt + L" to "Meta + L", or from using the new combination.

- Custom settings of the application:
The keyboard shortcut for locking the screen I had just finished changing from "Ctrl + Alt + L" to "Meta + L".
