[SciPy-User] notebook crash with fmin_lbfgsb

Just a general question:

Has anybody experience ipython notebook crashes with fmin_lbfgsb?

Is it just my setup or is this more general?
When I ran an estimation that uses fmin_lbfgsb for the optimization, then the notebook kernel shuts down and restarts.

(Windows 8.1, winpython 3.4, previous release of ipython, I think)

AFAIR, I didn't have problems with spyder
AFAIR, setting iprint=0 avoided the crash in the previous example, but doens't seem to fix it in my current example.

I switched to bfgs, which works well in my example

(aside: example is statsmodels ARIMA which uses fmin_lbfgsb by default)
