Creator can't import shadow build of Qt top-level build

1. Have a clean checkout of Qt 5's stable branch.
2. Have a shadow build of Qt 5's stable branch.
   I built using MSVC2010 and the configure switches

   -developer-build -opensource -confirm-license -opengl desktop -nomake tests -nomake examples
   

3. Open qt.pro from the repository mentioned in step 1 in Creator.
4. On the "Configure Project" screen, uncheck all suggested build directories and select the build directory from step 2 in "Import Build From...".
5. Click "Import".
   A message box will appear, stating: "No build found in C:\Users\rob\dev\bin\qt-5-stable matching project C:/Users/rob/dev/src/qt-5-stable/qt.pro."

Creator should be able to import such a shadow build. On a side note, the directory separators in the message box are really ugly.

I attached the Makefile from the build directory. This contains a relative path to the source directory although I called configure with an absolute path.
