Description
If blosc is installed show_versions() will caused python to produce a malloc_error_break (double free) error on exiting. This can be seen in the travis runs under source activate pandas && ci/print_versions.py section but can also be easily replicated on Linux and Mac. The fix for this is to replace imp (which has been deprecated) with importlib. I will create and link a PR.
>>> import pandas
>>> pandas.show_versions()
