Oh wait.  If the "catch-all plain text" filter is reached, it's supposed
to use the application type to decide in which app to open the file in.
So, if the file is opened from Writer it should open in Writer, and if
it's opened from Calc it should open in Calc.

Did that behavior change now?  If so, that'd be a regression from my
original intention.
