Application that crashed: konsole
Version of the application: 2.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686

What I was doing when the application crashed:
Konsole was open in a Ubuntu GNOME 2.28.1 session (not a KDE session) Several tabs were open and konsole crashed suddenly, the last command typed was 'host', I never had this problem before.
