So this looks like it might be a simple fix... in issue 1602, there was a patch for Windows console for 3.1... sadly not applied then, or 3.2, or 3.3 (yet). But in 3.2, the fix sprouted a failure just like this one: the console output class would get reported to not have an "errors" attribute when doing an input. A fix there was to add an attribute errors='strict' to the console output class.
Here it seems the same symptom sprouted in the same time frame, for a similar situation where the output class has been replaced by one that doesn't have an errors attribute... so it should grow one...
