Thanks for the report. Please search existing issues before taking time to write a report. This is a duplicate of #225, which has already been fixed (but not yet in master).

Sorry for the noise. I only searched the open issues ... :-(

No worries. I'm happy you contributed a report, but sad you did it after the issue was already resolved.
