Thank you for spotting this! That works of course.

I'm sorry, it seems I messed something up during copy/paste for my own 
backport version of this patch. Seems like I tested and sent a different 
version of the patch... That definitely shouldn't have happened :-(

Do you want to send that patch or should I?

Thank you again Fabio!
