mc & Segmentation fault

Some days ago i discovered something..If you export TERM with the name for
example "buqtraq" and you will start Midnight Commander you will see
something like this:

localhost:~$ export TERM="bugtraq"
localhost:~$ mc
Unknown terminal: buqtraq
Check the TERM environment variable.
Also make sure that the terminal is defined in the terminfo database.
Alternatively, set the TERMCAP environment variable to the desired
termcap entry.

But if the name of the TERM will include over 227 characters you will see
something different:
localhost:~$ export TERM="bugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraq
     bugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraq
     bugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraq
     bugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraq
     bugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraqbugtraq
     "
localhost:~$ mc
Segmentation fault
localhost:~$

I don`t know if it is interesting and i haven`t try do exploiting it but
maybe someone....
I have tested it only on Slackware 3.5.
