I've found this bug in konsole using vim.

If you open vim on a konsole, and you want to choose the size of the columns you just have to do

:set columns=x

where x is the number of columns.

With xterm (for example) when you choose for example 80 it automatically resize xterm to have 80 columns only.

In konsole it breaks vim and the konsole.

What I mean with "breaks" is that sometimes you cannot see what you type, ether in vim and in konsole, and also the reset command does not work, so you've to close the konsole.
