[Interest] Qml Compiler fails

[Jason H]

I added StyledTextField.qml to my qml.qrc,  when I compile now it says:
qtquickcompiler_loader.o: In function `QtQuickCompilerGeneratedModule::__StyledTextField_qml::createCompilationUnit()':
/home/jason/Projects/build-xxx-Desktop_Qt_5_4_0_GCC_64bit-Debug/.qtquickcompiler/qtquickcompiler_loader.cpp:467: undefined reference to `QtQuickCompilerGeneratedModule::__StyledTextField_qml::moduleFunctions'
/home/jason/Projects/build-xxx-Desktop_Qt_5_4_0_GCC_64bit-Debug/.qtquickcompiler/qtquickcompiler_loader.cpp:467: undefined reference to `QtQuickCompilerGeneratedModule::__StyledTextField_qml::qmlData'
qtquickcompiler_loader.o:(.data.rel.ro+0x320): undefined reference to `QtQuickCompilerGeneratedModule::__StyledTextField_qml::qmlData'

This is the first file I've added since switching to the QML compiler. I did a rebuild.  What is going wrong?
