Menu Block won't display when a page has a View Block on it
Well, it's an old question but I'll post what worked for me in D7 (since my views were already 'fields' as the OPs, but that didn't solve my problem).

I used the menu position module, and set rules for the content types that were being displayed via Views, I set their parent menu item and that's it. This makes the menu block treat any page with views as a normal page, and the menu block finally appeared correctly configured.
