[SciPy-Dev] SLSQP on Ubuntu

Hello I'm running SLSQP algorithm from Scipy on Ubuntu 12.04 and Python 3.3. The algorithm doesn't converge unless the starting point is really close to the solution. I tried it on Windows and it works perfectly, it converges easily and doesn't take too much iterations. On Ubuntu I either get the message "Inequality constraints incompatible", and sometimes I even get the message "Optimization terminated succesfully", but the values are not correct. Has anyone experienced the same thing? I have no clue to what's going on. Also I tried it with Python 2.7 on Ubuntu and still doesn't work, but on Windows it does. Thank you very much, I'm desperate.
