python not getting initialized bug in 2.0

[Anonymous]

With 2.0 version now receiving:
"Fatal Python error: PyThreadState_Get: no current thread"
on e.g. PyGettingStarted example

Appears that Py_Initialize is not getting invoked. Commenting out these lines fixes the problem:

  //if (flags & PythonAlreadyInitialized == 0) {
    Py_SetProgramName("PythonQt");
    if (flags & IgnoreSiteModule) {
      // this prevents the automatic importing of Python site files
      Py_NoSiteFlag = 1;
    }
    qDebug() << "Py_Initialize() start";
    Py_Initialize();
    qDebug() << "Py_Initialize() done";
//}

You are right, the correct line is

if ((flags & PythonAlreadyInitialized) == 0) {
…
}

I added this as a last minute feature and it broke PythonQt… I fixed it and uploaded PythonQt 2.0.1.
Lesson learned: Run your tests before releasing, even if it is late in the night…

At first I assumed this was a build problem on my end (e.g. pointing to incorrect dlls). I glanced over that code more than once before seeing the issue. So clearly the lesson learned is that C++ bitwise operators need to be given higher precedence ;-)
