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 2.6.30-ARCH i686

What I was doing when the application crashed:
I was editing files in a fairly large session ( ~50 files open at that particular moment) when I accidentially hit ctrl - enter, which send kate crashing. Operation prior to that point was normal and I'm not able to recreate the crash by typing the key combination in comparable circumstances, so the 
key pressing might have nothing to do with this particular crash.
