Description

Unable to launch an instance in RHEVM if encoded data is provided to it

Reproduction Steps:
==============
1. Setup dcloud on RHEVM configurations
2. From Images module, select an image and click on launch button
3. Provide the necessary details along with the "Base64 encoded user-data:" under the "Additional Properties" section and click on Create Instance button

Expected Result:
=============
Should be able to start the instance successfully

Actual Result:
==========
Throw stack trace stating "Deltacloud::ExceptionHandler::BackendError - Unhandled exception or status code (undefined method `[]' for nil:NilClass)"
Ref the screenshot "RHEVM-Encoded Data.png and below mentioned stack trace for further information

Note:
====
Able to start the image, if Encoded data is left blank.
