Description:

After upgrading to rxvt-unicode-terminfo-9.19-1-x86_64 from rxvt-unicode-terminfo-9.18-7-x86_64.pkg.tar.xz, tmux mangles the display in a rxvt-unicode terminal after resizing the window.

Additional info:
* package version(s): 9.19-1
* config and/or log files etc.

$ uname -a
Linux brentjenslaptop 3.12.6-1-ARCH #1 SMP PREEMPT Fri Dec 20 19:39:00 CET 2013 x86_64 GNU/Linux

Steps to reproduce:

- start Xorg session (Xfce + Xmonad)
- start urxvt terminal
- in terminal, call "tmux attach"
- open another window
- resize windows, making the terminal running tmux smaller to the point that it is narrower than the width of the tmux status bar.

The problem disappears when I downgrade to rxvt-unicode-terminfo-9.18-7-x86_64
