Views name must not contain space

Issue Summary

I added a table, created a view displaying its data, previewed and all was fine. Then I tried placing it as a block. Nothing happened. The Blocks page refreshed but the block was not placed anywhere. After some bug tracking I found that changing the name of the view, going back to the first step when Table Wizard created the view, solves the problem. The view name can't contain any spaces. So I think the validator at that step shouldn't allow spaces.
