PS:
Running application X built against Qt 4.5.x with Qt 4.6.x SHOULD work.
Running application X built against Qt 4.6.x with Qt 4.5.x WILL NOT work
(and this is why pushing apps built against a new Qt to stable BEFORE that
Qt gets pushed to stable is a bad idea, but rebuilding appliations for the
new Qt is normally NOT needed).
This is known as one-way (backwards only) compatibility, and quite common.
That said, some applications do need to be rebuilt due to backwards
compatibility issues, or get more features when rebuilt against a newer Qt.
But as you did not include a Bugzilla reference nor any other form of
rationale, I can't figure out why you rebuilt this particular application.
