I tested this and indeed it seems to fix the crash in the gallery and
make things operate much more smoothly. I'm +1 with the approach and so
is Florian.

Before we can land this, I'd suggest the following. Jussi if you or tstrehl could do this it would be good:
- [jussi/tstrehl] ask popey to see if he can grep through all of the core apps/apps in the store for the use of "image://thumbnailer" in the qml and if found make sure they are flagged to change add the import of Ubuntu.Thumbnailer.
- [jussi/tstrehl] send an email to the public phone list notifying folks of the change just to give a heads up. 
- [all] lets test other apps in the image (and scopes) to make sure nothing else breaks. I can help with this part.
