I have pandas 0.13.1 installed but pandas.read_stata() fails to read .dta files created in Stata 13 format, with the error
TypeError: cannot concatenate 'str' and 'NoneType' objects
No problem at all with the same dataset saved in Stata 12 format.
I thought that the latest release of pandas (0.13.1) handled Stata 13 dataset files. Can anyone help me with this?
