I'd say something is trying to call CFRelease on a null pointer.  The
followup question is to ask what function is calling CFRelease.

That's a great question. The only place the code has any call to
CFRelease is in the application's RegisterHelp method. The crashes I
am seeing seem to be totally unrelated to anything having to do with
registering help. So I assume it is either something in the framework
or in a plugin that is calling CFRelease.

I think it is probably in the framework. That is based on the fact
that in trying to track down this crashing problem I have seen reports
just like this several times, but have also seen a number of crashes
showing a problem when closing a particular window or trying to
refresh that window. I don't believe there are any plugins involved in
showing or closing that window. I'd really love to hear any further
ideas for tracking this down that you might be able to suggest.

The crash log should show what's calling CFRelease. That it's occuring so many times makes me suspect a stack overflow.
