But, on the other hand, as I've mentioned in one of my previous mails; the problem occurs in xterm and rxvt too. so I guess the problem is not with konsole, rather with some bash environment variable that has been misset.
That is why I asked about pure terminal as Konsole is a part of KDE in the X environment. Bash is the default shell even without X installed.
See if these help. However it could be a bug as you are using Debian testing. I had used Etch testing before it became stable and it was really weird.
