This works for mebut it opens up gimp (ubuntu 64bit) and previewer (intel macbook) as the graphics viewer, instead of a separate tab of firefox which is what it did before. I actually prefer the new behaviour (it makes my workflow a bit more efficient), but agree with you that something seems to have changed.
