QML examples fail to load on Windows

Steps to reproduce:

(1) Installed 358 MSVC 2012 binaries on Windows
(2) Open Qt 5 command prompt
(3) Go to any of the QML based examples
(4) Launch their executable

A window shows up but it shows no content and it is way to small (just the border is visible).

It appears to be a problem related to imports. Running the examples manually via qmlscene yields:

file:///C:/qt/Qt5.0.0-rc1/5.0.0-rc1/msvc2010/test.qml:1 cannot load module "QtQuick": File name case mismatch for "C:/Qt/Qt5.0.0-rc1/5.0.0rc1/msvc2010/qml/QtQuick.2/qmldir"

The same problem is also reproducible by creating a simple test.qml file, importing QtQuick 2.0, creating rectangle and trying to run it via qmlscene.
