[Ifeffit] Artemis: sum path NAN NAN NAN NAN

Hi guys, I've found a weird behavior in Artemis: during the fit procedure in the shell normally appears "sum path # # # #" where # = real number, but sometimes the minimization process fall in an infinite loop saying: "sum path NAN NAN NAN NAN". The only solution is to kill Artemis and restart. I've also observed that saving the project and/or removing all files in the .horae directory and/or changing the fit model temporary solve the problem. Well, it's not a problem to manage this "divergence"...
