rake:db:prepare Mysql::Error: #42000BLOB/TEXT column ' used in key specification without a length

I have a test environment running rails 1.2.3. I am just starting to introduce testing into this project. When I run a rake db:prepare. I see this message "Mysql::Error: #42000BLOB/TEXT column 'short_description' used in key specification without a key length: CREATE INDEX 'short_description' on cached_cars ('short_description')

The initial migration from the product displays this: #rake db:test:prepare --trace

Here is my environment. rake 0.8.4 ruby 1.8.6 (2007-09-23 patchlevel 110) [i686-linux] gem 0.9.4 rails 1.2.3

Any ideas???

Hi Will,

I was able to create another migration to drop that database and create it again with no indexes on these text fields. Once I did this all appears to be well.

Thanks Will
