Bug#384106: kopete: crashes whole system
> If it happens, kde hangs completely, leaving the user unable to switch to a

> Sometimes it is possible to ssh into the box from another box and kill kopete

This means surely that there is kernel bug! New kopete versions help to
trigger it, but the worse bug is surelly in the kernel.
Try to update the kernel (debian versions) and see it you see the bug.
In this case open a new bug (but now for the kernel) and help
to debug. (The kernel people will give you some hint how
to find more informations).
PS: to the maintainer: it is up to you if you should move the bug or
to let open in kopete. It is possible that a bug in kopete triggers
the kernel bug.
