Steps to reproduce:

  1. Have zsh as default shell.
  2. Open a new terminal. for example, with Ctrl+Alt+T.
  3. Press Ctrl+Shift+T to open a new terminal tab.
  4. ^T% appears as the first line

I'm running ubuntu 11.10 with lxde and zsh-4.3.11.

Gnome-terminal doesn't have this problem.

Post the content of your .zshrc, and /etc/zsh/zshrc. –  Gilles May 30 '12 at 1:24

That's an lxterminal bug.

It doesn't show in other shells because zsh is nice enough to try and show you hidden characters showed by the previous command when you don't include a trailing newline before issuing a prompt.

If you type echo -n foo, you'll see foo%. The % indicates that there was no newline character. Above, what happens is that lxterminal outputs that ^T before running the shell.

In other shells, instead of ^T%\nprompt>, you see ^Tprompt.

Lxterminal has another bug BTW in that it ignores the value of $SHELL.
