Qt/Nokia guarantees that an app compiled with Qt4.x executes with
Qt4.x+1, that is it will start up and will generally work, but you may
find behavioural differences sometimes. In what way those affect your
app depends on which classes you've used.

The other direction is only possible within patchlevel releases, so
compiling your app with Qt4.x.y and running it on Qt4.x.y-1 is possible,
but not running it on Qt4.x-1.
