An object must have a non zero positive mass m, other wise you get an infinite acceleration a, at a given force F:
a = F / m

We can see this problem on the particles of wind but it surely must be valid for all physical objects.
The problem seems to come from a defect in the resolution of Euler when a mass of an object is less than or equal to 0.
The question is ... an object with a mass <= 0 is it useful? why don't ban it and use the gravity parameter ?

guilty revision seems to be r6841.

Lami, as it is one of your commit, I let you debug it!

There is a big regression between 0.8.5 and trunk.

The display bug is particularly visible on map Cowland. I attach a screen-shot of the bug.

A "git bisect" is in progress to find the guilty revision...
