Attempting to pull my database from Heroku gives an error partway through the process (below).
Using: Snow Leopard; heroku-1.8.2; taps-0.2.26; rails-2.3.5; mysql-5.1.42. Database is smallish, as you can see from the error message.

The error:
$ heroku db:pull
Auto-detected local database: mysql://[...]@localhost/[...]?encoding=utf8
Receiving schema

17 tables, 9,609 records
