TortoiseHg asked me to report this bug. I use Windows 10 Pro. I was doing a Pull from a repository with Web Interface on a Linux machine over a VPN connection, I had done this before a lot w/o problems so far. Also I could complete the pull and I haven't really noticed any problems - other than this bug report.
