QClipboard causes unexpected recursion leading to crashes

QClipboard triggers the eventloop which causes unexpected recursion leading to 
crashes such as http://bugs.kde.org/show_bug.cgi?id=70430 

Although an attempt was made to stop the recursion somewhat by excluding 
several events (see below), this isn't enough.

qclipboard_x11.cpp:479
       qApp->eventLoop()->processEvents( QEventLoop::ExcludeUserInput |
                                          QEventLoop::ExcludeSocketNotifiers |
                                          QEventLoop::WaitForMore | 0x08 );

In particular, posted events such as DeferredDelete are still being processed 
due to processEvents() calling QApplication::sendPostedEvents()

Cheers,
Waldo
