i think i'm on it now :
- ----------------------------------------
void QLineEdit::clipboardChanged()
{
#if defined(Q_WS_X11)
    disconnect( QApplication::clipboard(), SIGNAL(dataChanged()),
        this, SLOT(clipboardChanged()) );
    disconnect( QApplication::clipboard(), SIGNAL(selectionChanged()),
        this, SLOT(clipboardChanged()) );
    deselect();
#endif
}

- --------------------------------------
it seems to be caused by this one (confirm ? ;p) 
but it looks correct to remove the selection when you select something in 
another app, so we can't simply remove the deselect() line
i think there is a wrong signal emit somewhere which causes a call to 
clipboardChanged() ...

if you look into the code you can see :
    connect( QApplication::clipboard(), SIGNAL(dataChanged()),
         this, SLOT(clipboardChanged()) );
    connect( QApplication::clipboard(), SIGNAL(selectionChanged()),
         this, SLOT(clipboardChanged()) );
in copy()

dataChanged() is emitted by the clipboard itself (kernel/qclipboard_x11.cpp)
selectionChanged() is defined in qlineedit and emitted quite some times

we need to go deeper in that way i think...

cheers,
Mik
