Hi,

I have an idea on how to implement it without complicating ev-window too
much. Maybe we should use a generic error widget, there are possibly
other cases when this could be useful.
Basically I think we should assimilate this case to the no document
case, destroying the document (maybe unparent the view or destroy it,
unsure yet) and packing in the error widget instead. I think then it's
enough to check the existence of the view in the _open code, and stuff
should work.
Maybe not super clean but a start ;)
