A malformed request to the filter form of a view produced a crash report with a bare AssertionError instead of an error message. This could be seen after a browser reload during an upgrade, when the page and the server disagreed about the format of the request.

Such a request is now answered with the message "The request is missing the filter infos to render" and no crash report is created.
