name 'r130' not defined

I’m trying to get the vdirsyncer iCal server working but when I run the discover command I get an error.

> vdirsyncer discover iCloud_to_MagicMirror

Discovering collections for pair iCloud_to_MagicMirror
Mirror:
  - "01E5BA92-D478-4EDE-BA58-AA3F6424AD40"
iCloud:
  - "01E5BA92-D478-4EDE-BA58-AA3F6424AD40"
error: Unknown error occurred: name 'r130' is not defined
error: Use `-vdebug` to see the full traceback.

Anyone know what this is??
