I worked out the problem.  Looking more closely at the crash log:

Thread 5 Crashed:

1   com.apple.CFNetwork                 0x96f719f3 JSObjectIsFunction + 190

I noticed reference to a proxy.  The problem only manifests when you're behind
a proxy server.  I use a PAC file so that when I access online scientific
journals, I get routed through Stanford, and thus have Stanford access to those
journals.  I just removed the reference to the PAC file in the system
preferences, and the crash no longer occurs.  If it's relevant, the PAC file
(referenced by URL) is:

http://library.stanford.edu/apcproxy/suproxy.pac

I presume this means the bug is in CFNetwork, not Webkit, and that I should
file a radar, and this should be marked as INVALID?

I've noticed at least two other bugs in Leopard with regard to PAC files (Adobe
updater takes up all available RAM behind a proxy, and dmnotifyd also takes up
all available memory after waking from sleep (see
http://discussions.apple.com/thread.jspa?threadID=1287849&tstart=0)), so these
may all be related.
