PHPStorm + Remote PHP Interpreter: PS is trying to create .phpstorm_helpers in the wrong place

Hello,

I'm (still) trying to setup Xdebug in combination with PHPStorm 2016.1.

When I select the PHP binary and finally click on the "reload" icon I get an error message:

Well PS is right, it can't create a directory in /
But why isn't the IDE using the users home directory?

Best regards
