  nova --debug image-list was OK

  I could reproduce this error with curl.
  curl -H "x-auth-token: XXXXXXXXXXXXXXXXXXXXXXX" https://nova-api.trystack.org:9774/v1.1/1/servers/detail --insecure
  {"cloudServersFault": {"message": "The server has either erred or is incapable of performing the requested operation.", "code": 500}}

  
  Then I checked instance name,
  SELECT id,display_name FROM `instances`

  Then I found an instance use uft08 char in display name.
  I removed this instance, then nova list command back to normal.

  nova-api should check UTF8 char in parameters
