Creating new R environments displays an error, but conda is still working behind-the-scenes

[xpros]

Hello!

We are working on upgrading our JupyterHub instance to use version 0.9.1 and Conda version 4.5.8.

The issue we are seeing now relates to creating a new R environment through the Conda tab while using JupyterHub. Conda and R historically seems to take a LONG time to create a new environment because Conda has to solve all of the package specifications.

When creating a new environment, it throws and error:

BUT, if you check running processes on the host conda is still working and eventually creates the environment.

Additionally, similar behavior is observed when cloning an environment through the UI.
