Just another data point: I have two machines with identical OS's (Mac OS 1.8.4) and identical installs of 1.6.1. The MacBook Pro (mid-2012) has no problems with window resizing. The Mac mini (late 2012) consistently throws a kernel panic on resize.
No surprise, but noted that it occurs on LAN worlds as well. My 7 year old discovered this bug within two hours of updating – it's not likely to go unnoticed!
