I made a new executable from the current CVS, and even without the patch it did not
crash anymore.
For some reason, it how uses '-lcurses' instead of '-ltermcap'.

I did some tests with the debugger.
The crash happened because getenv("TERM") returned 0 during the call to tgetent from
the termcap library.
Whithout the patch, getenv("TERM") still returns 0, but now tgetent from libcursus.a
is used.
With the patch, getenv("TERM") returns "dumb" before tgetent is called, so I guess it
will also be fine for tgetent from the termcap library

Andrey,
thank you very much for your time and effort.
