patch for segfault

[Joaquim Fellmann <joaquim hrnet fr>]

Hye, this patch is the only way for me to send email again with balsa
(have a look at the previous mail I sent on the list)
Can any developper apply it or tell me what's wrong with it. 

PS: of course it doesn't explain why the variable had a NULL value but it
prevent balsa from accessing a NULL pointer.

Thanks
