Bug fix, provided by Martin Dickopp;
The dynamical allocated arrays (rwenzlaff, april 03) for render vertices/ faces/halos were freed in a way that requires the last element of array to be NULL. This wasn't coded however, causing memory errors in exceptional cases; like when amount of faces/vertices is exact between 261888 and 262144. :)
