Application that crashed: kate
Version of the application: 3.2.98
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-14-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
As usual, I was working with a group of files opened in Kate, all of them managed by a session. I modified a single file and after I clicked in the Save button (on the toolbar) Kate crashed. This is the first time it happens to me, at least in the KDE4 era.
