Application: konsole (2.4.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-27-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
If I try to assign Alt-F12  as the access key for a profile, Konsole warns me with a popup "Conflict with global shortcut - Konsole" that this key is already assigned in application "KWin" to action to "Mouse emulation". If I click the left button "New assignment" of the popup, Konsole crashes. Backtrace is attached.

The crash can be reproduced every time.

 -- Backtrace:
Application: Konsole (kdeinit4), signal: Segmentation fault
