Ok, so the source you gave is a pretty invalid one, the QQuickImageBase - without the toolkit extension - reports that the source had changed, and changes the url, but the actual image is never changed/unloaded, because they also do QQmlFile::urlToLocalFileOrQrc(url), which will cut the #1450427565454 from the end.
In our case, we call this method way before we pass the given url to the QQuickImageBase, therefore the source change does not happen.
