Hi Cedric, thanks for the report.
Is it possible for you to submit a bug on Mantis? -> Looking at the code of the application I see also other point that could be improved regarding anisotropic diffusion filtering in the application. It would be easier to investigate. I am not sure to understand in your mail the value for time step. I don't think that it could/should be negative.
