hi, we detect a strange issue on Pandas-0.19.1/Python-3.6.0b3/Windows that may or may not be a Python-3.6 bug. 
As it was for the glory of Python-3.6.0b3 testing, we signal the incident here.

Extract of the bug report:

> ...
> pandas/tslib.pyx in pandas.tslib.convert_str_to_tsobject (pandas/tslib.c:26851)()
> pandas/src/datetime.pxd in datetime._string_to_dts (pandas/tslib.c:87106)()
> SystemError: <class 'str'> returned a result with an error set

It looks like a bug in a C extension, I mean in the third party code.

the curiosity is the error message, different (and uncaught) under Python 3.6
"SystemError", while with python < 3.6, you get a "ValueError"

> while with python < 3.6, you get a "ValueError"

It's because Python 3.6 is more strict. Python 3.5 doesn't catch the bug.

Thank you, Victor. So I guess I should close the issue.
