How to reproduce: Go to the history of page and check a checkbox and press "Show/hide selected revisions". Choose what you want to hide and press on "Apply to selected revision" Actual result: revision is hidden, but "Fatal exception of type MWException" is thrown to you instead of the page that confirms that you hid the revision. Expexted result: It should show the page to confirm you hid the revision.
