Electrum-Keepkey Issue

Examining Electrum-LTC 2.6.4.2 to seup a New OR Existing Keepkey wallet I get the following:

Error - Could not parse protocol buffer message

… however Trezor works fine. Wondering if others have seen this issue.

UPDATE: This issue has been resolved with Electrum V 2.8.3.2 however as noted in another post I can’t Sign w/either Trezor or Keepkey using V 2.8.3.2.
