Fatal error when using "Event series start date" filter in views

I've added the "event series start date" as a field in a view.
However, when i do any kind of exposed view operation, I get the error below.

I'll attach a patch that fixes the issue in the query. Please review carefully, as I'm a bit confused if this is the right approach.
