Not so easy, the machine isn't online for long -- if it's on at all
(quite noisy) and isn't reachable from the internet (NAT).

However, I've found something, breakpointing the prbf caller, gdb
backtrace and fis_stats info below.

So the problem might be in rob_compute_spamicity or fis_get_spamicity;
needs further investigation; anyways the P input that is passed to
fis_get_spamicity differs.

### LINUX:

0}, Q=

Still no idea what's really going on there.
