Comment # 6 on bug 1054509 from Andre Lopes da Silva

Noticed that yesterday on my desktop Tumbleweed while trying yast at terminal.
(XFCE4-terminal)

My notebook (also Tumbleweed) wasn't updated for a few weeks and was ok, but
the exact same error appeared after zypper update (LXDE-terminal)

Today I tried to install a fresh Tumbleweed (up-to-date Net installer iso) on a
KVM virtual machine and confirmed it also happens on a fresh install (LXDE
Terminal)

Suggested workaround works - "TERM=linux <command>" ("TERM=linux yast" in my
case)
