Package: bogofilter
Version: 1.2.0-1+b1
Severity: important

It seems like bogofilter crashes on some mails, i get the following backtrace
when rebuilding with debugging symbols:

(gdb) 

The compare_rstats_t function doesn't seem to cope well then the probabilities
are incomparable and one of the sides doesn't actually have tokens...
