freebsd stable - Oct 2009 - NULL-pointer reference in ulpt

I didn't get any replies to my previous report, so I'm trying again. I  
frequently get a kernel-panic after printing something to my USB  
printer (A Samsung ML-1210). It looks like usb_setup_xfer() is called  
with a NULL-pointer for xfer from ulpt_tick().

System is a 7.2-STABLE, last updated on Sep 15. I just did a make  
update, but there were no changes to ulpt.c.

Can you try this in 8.0? The USB stack is very different there (and much  
better in a lot of ways).
