--- Comment #5 from Krzysztof Halasa <khc at pm.waw.pl>  ---
This problem seems to be caused by buf[4096] (file scripts/kconfig/mconf.c)
overflow. Function cprint() seems to write past end of buf - overwriting, for
example, do_resize variable, thus causing the dialog to fail.

Changing to buf[8192] seems to help for now, though I'm not exactly sure it's
the best way to fix it. Perhaps some improvements can be imported from Linux'
kconfig.
