Hi Blake,

Also include an optimizer trace would be useful:
http://dev.mysql.com/doc/internals/en/optimizer-tracing-typical-usage.html

I suggest you to report a bug on this, including CREATE TABLE, data generation script and the affected query and post the bug number here.

With that info it is easier for us to debug and find a solution for you.
