This is indeed only on Win32. I receive the VTK error in
VTK\Rendering\vtkWin32OpenGLRenderWindow.cxx::MakeCurrent() at line 215:
         vtkErrorMacro("wglMakeCurrent failed in MakeCurrent(), error: "
                       << (LPCTSTR)lpMsgBuf);
         ::LocalFree( lpMsgBuf );
This only happens when MakeCurrent is called from 
vtkWin32OpenGLRenderWindow::Clean() (i.e. when the window gets closed).

Best regards,
