scrollRangeToVisible from within mouseDown causing crash?

I just added a call to scrollRangeToVisible: that is sometimes called 
from my text view's mouseDown method.  Now, whenever 
scrollRangeToVisible: is called on a range that is not visible, the 
next drawRect of the text view crashes with the exception: "*** 
NSLayoutManager, _getGlyphBuffer(): NSZoneMalloc 
failed!" (EXC_BAD_ACCESS).  I had assumed that this was just a memory 
management bug on my part, but the fact that I can basically turn the 
crash on or off based on whether I call scrollRangeToVisible has me a 
bit confused.  Anyone know what this could be?
