Segmentation fault error when attempting to use snowflake connector

Hi,

I'm attempting to use the Snowflake Connector for Python, as such:

`using PyCall
@pyimport snowflake.connector as snowflake
conn = snowflake.connect(user="user", password="pw", account="account") `

However, not able to connect due to a segmentation fault.
Additionally, this is only showing up for me when using Julia 0.6.2 (previous versions are not giving me this error). Appreciate any input.

This is in the stack trace:
```Program terminated with signal SIGSEGV, Segmentation fault.
