Application that crashed: kate
Version of the application: 3.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
OS: kubuntu 9.10
uname -r: 2.6.31-14-generic
on a Toshiba laptop satellite M-100 series
Kate: Version 3.3.2
KDE: 4.3.2

Kate simply crashes after collapsing top leves with Ctrl + Shit + - and pressing either 'up' or 'up-arrow' keys. It is consistent.
