Description
When I start the application on a headless machine, as some of our servers do not have monitors, the application crashes. I use teamviewer/vnc to graphically access these servers. Starting from:
QApplication a(argc, argv);
I have tracked this down to a core file call qxcbconnection.cpp and the line:
xcb_create_window(m_connection, XCB_COPY_FROM_PARENT,
m_connectionEventListener, m_screens.at(0)->root(),
0, 0, 1, 1, 0, XCB_WINDOW_CLASS_INPUT_ONLY,
m_screens.at(0)->screen()->root_visual, 0, 0);
The problem is, if there is no monitor connected, then m_screens is empty, and therefore causes an “index out of bounds” error.
