crashing python file

Attached code crashes on pySide 1.0.0beta1 when clicking the 'read files'
button (might need few clicks before crash) 
Tested with binary package downloaded from:
http://developer.qt.nokia.com/wiki/PySideBinariesMacOSX). 
This code didn't crash with pySide 0.4.1 package.

OS X version: 10.6.5
QT 4.7.1 commercial.
I had about 25 files in directory in this crash example.

Clicking the 'read files' button gives output to terminal:
