Remote interpreter - Run With Coverage fails with "Unittests_in_tests: Undefined variable"

Hello,

Currently I'm able to use my remote interpreter to run things just fine. But if I try to run something with coverage I wind up with this:

"Unitests_in_test_file_name_py: Undefined variable."

Note: In the following log entries I've replaced certain things like usernames, server names, and script/file names.

The full 'run' tool output is:

First issue I see is that it's passing local Windows paths to the remote Linux server. Looking at idea.log I see this line:

Formatted a little nicer:

Again, passing Windows paths to a Linux machine. A variable is referenced here: '$Unittests_in_test_file_py' which eventually results in the error above. 

Any ideas on this? I've looked at the issues recommended by Anna Morozova here but they weren't of much help.
