Bug in QEventLoop in Qt3.1beta

[Lubos Lunak]

 Hello,

 if QApplication::eventLoop() is referenced before QApplication is created 
(e.g. when creating a QSocketNotifier, as in kded when fam daemon is running 
or dnotify support is enabled), it doesn't add the X11 connection fd to the 
list of watched fd's (because there's no QApplication instance at that time). 
Later this causes crash when qt_gui_is_used becomes true but d->xfd is still 
-1.

 The attached patch should fix the problem. You'll also have to do something 
with QEventLoop::appStartingUp() in qeventloop.cpp .
