Here's the code I have for Editor::eventFilter() in editor.cpp:

bool Editor::eventFilter( QObject *o, QEvent *e )
{
    if ( ( e->type() == QEvent::FocusIn || e->type() == QEvent::FocusOut ) &&
	 ( o == this || o == viewport() ) ) {
	accelUncomment->setEnabled( e->type() == QEvent::FocusIn );
	accelComment->setEnabled( e->type() == QEvent::FocusIn );
    }
    return QTextEdit::eventFilter( o, e );
}

I can't see a lot that could go wrong there, and as it crashes in an X11 font 
lib I would have thought it's more likely that there's something wrong with 
your font setup than pqt-designer. But then why would pqt-designer crash and 
not other apps?
