Comment 4 for bug 458524

Experiencing the same bug reproducibly on Karmic Server 9.10 AMD64
When using aptitude and selecting any item with the 'Enter' key (after pressing 'u' for update), aptitude crashes with "Uncaught Exception: Unable to read from stdin: Success"

Afterwards, my tty1 is rendered unusable:
Suddenly, the prompt becomes "root@mycomputer" instead of "username@mycomputer" and every key has to pressed twice to appear on screen.
Logout with CTRL-D is possible, but unusable - commands are misrecognised: exit as xit, or similar.

Changing to tty2 with ALT-F2 works. No log entry in /var/log/messages or /var/log/aptitude.

ALSO appears when using apt-get directly! (Some error in red background about a maintenance shell, will post it as soon as I see it again)

Can confirm the issue wirth control characters of clarox: Bash history gives me sometimes control chars instead of the last command typed.

Hope, this is might help you :)
Will be happy to provide further information, if you tell me how to give it to you ;)
This really is a nasty bug, renders the server almost unusable.
