The cumulative distribution function of geninvgauss is outputting values slightly greater than 1

Hi,

fitter outputted the following best fit parameters for a geninvgauss distribution:
(0.48753085620446013,
5.181675881089951e-11,
0.00015499999999999997,
2.953504104288843e-14)

For these parameters, dist.cdf(0.05, *params) = 1.0000000000930243 is slightly above 1, so the above cannot be right?
