What's This crashes on Mac OS X?

Code:

---

#include <QtGui>
int main(int argc, char *argv[])
{ 
    QApplication app(argc, argv); 
    QDialog dialog; 
    dialog.setWhatsThis("what?"); 
    return dialog.exec(); 
}

---

Steps to reproduce

1. Compile and run the application shown above
2. Press Shift+F1

Expected behavior

• yellow box with "what?" is displayed

Observed behavior

• Windows 7 x64: as expected
• Ubuntu 10.04 x86: as expected (might have white font)
• Mac OS 10.6.2: yellow box with "what" displays for a split second, then app crashes
  
  • crashes for both Qt 4.7.4 and 4.8.3

Am I missing something here?

Alternatively, short of recompiling from scratch with QT_NO_WHATSTHIS, is there any way to disable What's This for my entire application?

Thank you!!

It's ugly even as kludges go, but installing an event filter for Shift+F1 on the QApplication object seems to gets the job done...there's gotta be a better way, right?
