Curvey Corners - Error: Radius exceeds box width

[garetha]

I have a Rails(2.3.8) app, which is being tested with Cucumber & Capybara with the capybara-envjs web driver. I am getting this error "Radius exceeds box width".

I have narrowed this down to CurveyCorners - this error doesn't occur in the browser so it must be something to do with the way the driver runs the test. Is there a way to get it to ignore this type of error?

I don't know what is generating the error but it sounds like a check of layout/rendering values and env.js doesn't support rendering so I don't think this is going to work.
