Version:           2.2.1 (using KDE 4.2.1)
OS:                Linux
Installed from:    Debian testing/unstable Packages

I use bash as my system shell. When i starts konsole and any application in it, this application often doesn't react if i press ^C or ^\ to break it; when i logging out, using ^D - konsole closes bash-session, but doesn't close tab with this session. After some (4-5) restarts it works fine.
Same if i use yakuake.

$ bash --version
GNU bash, version 3.2.39(1)-release (i486-pc-linux-gnu)
