  BUG: test_numerical_operations fails under pandas 1.1.0
  [Failure](https://travis-ci.org/github/geopandas/geopandas/jobs/712675986#L2140) in `test_numerical_operations` (`idxmin` error type) -> pandas-dev/pandas#32749. Even though it is a known regression in pandas, we should handle it (at least skip tests for now).
