UPDATE: Segfault when using -vv or -vvv

[Mike]

OK, I just populated my db with only ham initially, after populating  
with spam as well, the segfault disappeared.

However, I populated ham and spam with the SAME corpus and got this as  
a result:

    int  cnt   prob  spamicity histogram
   0.00    0 0.000000 0.520000
   0.10    0 0.000000 0.520000
   0.20    0 0.000000 0.520000
   0.30    0 0.000000 0.520000
   0.40    0 0.000000 0.520000
   0.50    0 0.000000 0.520000
   0.60    0 0.000000 0.520000
   0.70    0 0.000000 0.520000
   0.80    0 0.000000 0.520000
   0.90    0 0.000000 0.520000

I ran the spam and ham commands only once each on a new DB.
