Description of problem:
When navigating to the plugin page, there are 3 active buttons for viewing diffs. They are active regardless of whether there are plugins installed or not.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.install base iso image
2.navigate to the plugin page
3.select one of the diff view buttons
One of a few things can be done:
1. Disable the buttons if there are no plugins installed
2. Don't make display the plugin page available or visible unless there are plugins
3. Add high level logic to the plugin page to show something like: "There are no plugins currently installed" and that's it
4. Catch the error and handle it
Preference would be for #1 #2 or #3, but rather indifferent to which one.
The fix for this patch has been merged and is present in the released ovirt-node-3.0.0.
