After click on Delete button empty modal window

[VerSooSet]

What I did:

Trying delete theme plonetheme.business.casual
screenshot

What I expect to happen

deleting modal dialog

What actually happened:

the script was partially executed. Perhaps something was wrong and istead off message_text returns empty string. Besides if the dialog is closed on 'x', then the window disappears and the dark background remains. I have it only at new uploaded theme except copy of barcelonetta.

What version of Plone/ Addons I am using:

Plone 5.0.4.

The problem is described in more detail on #115. And that is a same another view only. Happened to solve it manually as the same way which described.

The issue is still around in 5.1.2. Thanks @tkimnguyen for the link to the workaround by deleting or renaming the theme under portal_resources in the management interface. Would the fix by @gp54321 be accepted or are there any concerns?

[tkimnguyen]

@philipsahli I just ran into a similar problem because a theme had a space in its name or ID. If @gp54321 could make this a pull request?
