[BareMetal] errors with the opening a custom QBS project

This continuation of the thread begun on mail-list, can be found here:

Short prehistory:

I try to use the BareMetal plug-in from the QtCreator for creation a
project for the STM32F4DISCOVERY board with use the QBS on the Windows
host PC.

Note: To the attach added the archive of the minimum source project (qbststapp.zip).

Steps to reproduce a problem:

1) Add a custom GCC compiler and specify a path to him, e.g.:

• Name: ARM-GCC
• Compiler Path (in my case): C:\Program Files (x86)\GNU Tools ARM Embedded\4.72013q3\bin\arm-none-eabi-gcc.exe
• ABI: arm-unknown-unknown-unknown-32bit

2) Add a custom GCC debugger and specify a path to him, e.g.:

• Name: ARM-Debugger
• Path (in my case): C:\Program Files (x86)\GNU Tools ARM Embedded\4.72013q3\bin\arm-none-eabi-gdb.exe
• ABI: arm-unknown-unknown-unknown-32bit

3) Add a custom Kit:

• Name: ARM-kit
• Device type: Bare Metal Device
• Device: Bare Metal Device (default for Bare Metal)
• Sysroot: Empty
• Compiler: ARM-GCC
• Debugger: ARM-Gebugger
• Qt version: None
• Qt mkspec: Empty

Note: I.e. in my case available only one Kit!

4) At trying to open a "Bare Metal" QBS project (from an attachment) I got an error:

"C:\Qt\qt-creator-debug-git\share\qtcreator\qbs\share\qbs\modules\cpp\windows-mingw.qbs:7:
error: TypeError: Result of expression 'qbs.toolchain' [undefined] is
not an object."

Thus opens the file "windows-mingw.qbs" and the marker is set on a
condition:

import  qbs1.0
import  qbs.FileInfo
import  '../utils.js'  as  ModUtils
import  "windows.js"  as  Windows

GenericGCC  {
==>   condition:  qbs.targetOS.contains("windows")  &&  qbs.toolchain.contains("mingw")

...
...
...
}

5) Next, I tried to delete modules the "windows-mingw.qbs" and the
"windows-msvc.qbs" and re-open the project.
But in this case I got an other error:

"E:\git\ng\git\qbststapp\qbstest.qbs:5: error: Module cpp could not be
loaded."

Thus opens the qbs file of my project and the marker is set on "depends":

import  qbs1.0

Product  {
      type:  "application"
==>   Depends  {  name:"cpp"  }
...
...
...
}
