I can confirm that this did not happen during silo testing, with a clean
device-flash'ed image + ppa on top.

As a side note, we're adding click hooks to clean up the cache environment
of webapp-container based apps, ie webapps. This is to avoid cases where
the application sets cookies and gets confused, essentially locking the
user in a broken situation. With those hooks, by removing the app, the
package also clears cached elements, which helps getting back to a saner
state, once reinstalling the app.

I think the QML cache should be part of the things to clean at app
uninstallation, but would like to know if a generic framework will be put
in place, or whether we should just add this directory to our list for the
time being.
