Now I have a case:-))

$ bogofilter -o 0.7,0.2 -vM <spam
X-Bogosity: Spam, spamicity=1.000, version=0.96.5
X-Bogosity: Unsure, spamicity=0.695795, version=0.96.5
$ formail -s bogofilter -o 0.7,0.2 -vM <spam
X-Bogosity: Spam, spamicity=1.000, version=0.96.5
X-Bogosity: Spam, spamicity=0.955, version=0.96.5

As you can see, the second message is rated differently.
When I delete the first message from file, everything is
fine again.

Note: When I was looking for the testcase, there have been
several messages between those two messages above. So
somehow bogofilter -M gets out of step.
