Comment 3 for bug 160720

I have en_GB and couldn't reproduce the bug. I tried between irssi and xchat
$ apt-cache policy irssi
irssi:
  Installed: 0.8.12-4ubuntu2
  Candidate: 0.8.12-4ubuntu2
  Version table:
 *** 0.8.12-4ubuntu2 0
        500 http://de.archive.ubuntu.com intrepid/main Packages
        100 /var/lib/dpkg/status

gnome-terminal:
  Installed: 2.24.1.1-0ubuntu1
  Candidate: 2.24.1.1-0ubuntu1
  Version table:
 *** 2.24.1.1-0ubuntu1 0
        500 http://de.archive.ubuntu.com intrepid-updates/main Packages
        100 /var/lib/dpkg/status
     2.24.1-0ubuntu1 0

Does this still occur? Do you know if it's related to the irssi package?

Can you post the output of the command:
apt-cache policy irssi gnome-terminal

Can you try with Ubuntu 8.10 intrepid ibex or with the release in development, Ubuntu 9.04 jaunty?
