    Unfortunately, this is a known problem when using help on Python. It currently has to import modules to inspect their docstrings and this may result in crashes if the modules execute code upon import and call third-party libraries that expect a certain execution context or that may just be buggy. Here’s an open Ubuntu issue about this specific case. There are a number of open issues in the Python issue tracker about similar crashes due to help importing.
