Hi Matthias,

All the 29 test cases of qqmlmoduleplugin succeed for me (MSVC2010-32 bit, MSVC2010-64 bit and mingw-32 bit running on Windows7). This is with qt5-beta1. Output for the first test case (with set QML_IMPORT_TRACE=1) is

********* Start testing of tst_qqmlmoduleplugin *********

How did you configure your Qt ?
