caused by itunes connecting to iphone 3G (good ole locked at 4.2.2 one)
it does this once or twice, before it grabs device and mounts it into itunes. i don't know if this is just itunes getting impatient with a device that's slow by comparison to newer models it was expecting.
on plus side, the new update seems to have fixed the other error that's spam console every minute endlessly for entire duration a device was plugged in

I tried something else.  I created a new account on my computer, launched itunes, and plugged in the iPhone 4.  The summary screen came up.  I subscribed to a podcast, clicked on the iPhone (not crashed) and synched podcasts.  Synch completed ok.  Other iPhone content is not affected. 
So something is wrong with my account on this computer?  Where are account stuff stored for an iPhone or iTunes?  Or is it something else? 
Thanks for any input.
