The test produces a traceback while shrinking a window (increasing the window size works ok):

Traceback (most recent call last):
  File "screen-resize-bug-curses.py", line 22, in <module>
    curses.wrapper(main)
  File "/.../python2.7/curses/wrapper.py", line 43, in wrapper
    return func(stdscr, *args, **kwds)
  File "screen-resize-bug-curses.py", line 17, in main
    init_display(stdscr)
  File "screen-resize-bug-curses.py", line 9, in init_display
    rootwin = stdscr.derwin(20, 50, 0, 0)
_curses.error: curses function returned NULL

Version info:

$ python2.7 -c'import curses; print curses.version'
2.2
