Description of problem:
(see image) The Error message that UI prompts after a failure to create template because of a broken volume chain,"Error while executing action New VM Template: Image is not a legal chain",is very unclear,I'm certain an average user will find it hard to understand.

Version-Release number of selected component (if applicable):
rhev3.5 vt2.2

How reproducible:
100%

Steps to Reproduce:
Setup:have an image with a broken volume chain attached to a vm

1.create a template out of this VM

Actual results:
An unclear ERROR message

Expected results:
The message should be more comprehensible,like,"Error while executing action create new Template:image data is corrupted".

How do you produce such a scenario?

In short - it does not happen in any reasonable usecase.

Images are assumed to be OK.
If a customer encounters one that isn't, he should contact support and get it fixed - we aren't going to start dealing with them in every flow.
