Same here (MacBook Pro, Intel Core 2 Duo, Mac OS 10.5.6 with Preview  
4.1), although it seemed to happen about halfway through the indexing  
process for me.  Preview hangs with full CPU load and has to be  
killed.  "sample" shows that two threads are waiting for a signal,  
while the third thread (the indexer) is busy normalising and "adding"  
text regions.

I suppose that Preview has got stuck in an infinite loop, but don't  
know how to figure out where in the document this occurs (or what the  
root cause might be).  Definitely a bug in Preview, though.

Best,
Stefan
