I get this error in tail log, and it seems like it´s happening everytime I´m navigating through Things in Habmin.
I have no idea why. And I can´t really see any symptoms either, except for the log ofcouse.

This occurs for all Things, not just zwave. I assume it is something to do with i18n. My laptop is using Firefox on Fedora27, and my locale in OH is set to United States/English. I have also seen the same with Chrome on Windows 10.
