[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

EDIT(other user): The crash actually happens when the terminal window is
too small.

When I try to download a big file with wget on Ubuntu 16.04 it crashes
after a couple seconds.

To reproduce the bug try the following:

wget http://releases.ubuntu.com/16.04/ubuntu-16.04-desktop-amd64.iso

I've asked another guy on IRC on channel #ubuntu-it to try and reproduce this bug
and he said it was crashing also on his machine.
