Application that crashed: kate
Version of the application: 3.3.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I was coding in C when i needed to enter "\n", which on my german keyboard is lolcated at <Alt Gr> + 0. My finger slipped and i typed <select> + 9.
Kate crashed.
By <select> i mean the button that is on some keyboards adjacent to <Ctrl> and <Alt Gr> and opens the context menu on most occaions.
