[New-bugs-announce] [issue6243] getkey() can segfault in combination with curses.ungetch()

[Trundle]

New submission from Trundle <andy-python at hammerhartes.de>:

Snippet to reproduce:

import curses

scr = curses.initscr()
curses.ungetch(1025)
scr.getkey()

This is because `keyname()` in `PyCursesWindow_GetKey()` returns NULL
which is passed to `PyString_FromString()` then.

The attached patch fixes the segfault.
