Segmentation fault in QScrollView

Hi,

I'm having some problems with a QListBox object.  The ListBox contains 
any subdirectories in the current directory, and by clicking on an 
entry, changes to that directory and redisplays itself. The basic 
functionality is fine. However, intermittently the program causes a 
segfault and crashes.  The last piece of Qt debug output to be received 
is:

virtual 0x8814988->QScrollView::resizeContents() called

0x8814988 is areferring to the QListBox object. It is random as to 
which directory and how many times it will change directory before it 
crashes. I'm using the PerlQt bindings (3.008), and running Qt version 
3.1.2 (also tried 3.1.1).

Has anybody encountered this before?
