Thanks from the report. Could you please tell how you use Open Browser keyword and was the Selenium version you are using?

[chaussen]

selenium (3.5.0)
Open Browser ${URL} browser=ff

1. What's the actual exception you got? The included traceback shows where the exception occurs but not what the exception is.

2. Could you test with other Python 3 versions than 3.6?

3. Could you test this with Selenium only?

I can reproduce this problem with Python 3.5 Selenium2Library. Need to think what causes the problem.

Fixed in #881
