Default Calibre device detection on 5.3-beta fails with python error

Keep getting python errors when calibre trys to run the device detection routine. Pasted below is the error as pulled from Calibre => Preferences => Misc => Debug device detection. This happens when running calibre with root permissions too.

Application author does not provide support for BSD but welcomes patches.

calibre, version 0.8.20
