Opening a view or dashboard whose saved context stored a filter value directly, instead of the set of filter variables Checkmk expects, crashed the page with AttributeError: 'str' object has no attribute 'items' while building the links to related views. The same entry crashed the breadcrumb and the page title with AttributeError: 'str' object has no attribute 'get'.

Such an entry is now left out. The page renders again, and the other filters are still passed on to the linked view.
