Registering a 2.0 QML type before a 1.0 version breaks import of 2.0

Registering the 2.0 version of a type before 1.0 causes "import ModuleName 2.0" to pick up the 1.0 version:

qmlRegisterType<BuggyVersion2>(uri,2,0,"Buggy");
qmlRegisterType<BuggyVersion1>(uri,1,0,"Buggy");

import Qt 4.7
import BuggyModule 2.0
Buggy {}

Reversing the order of the registrations fixes the problem. See attached example.
