I pressed Alt+Ctrl+Shift+Down on an Ecore model element in the context page of the task editor. java.lang.NullPointerException at

This is probably a consequence of the key binding issue.
Looks like the equals comparision should be reverted.
Well, content type should never be null in any case, right? I wonder if this isn't related to the corruption in bug 357768
OK, I won't be cute and say that this is no longer an issue because we got rid of the key-binding. :) But I tested by invoking menu item and it seems to work fine.
