table_name_prefix breaks rake db:schema:load

Setting a table name prefix in my environment.rb file breaks db:schema:load, example:

    config.active_record.table_name_prefix = "translator_"

After I run db:schema:load, my tables load fine, but my translator_schema_migrations table contains only 1 row, and the row's version column is set to "0". I added some print statements to the assume_migrated_upto_version(version) method to see what the problem was:

def assume_migrated_upto_version(version)
        puts "Version Before: #{version}"
        version = version.to_i
        puts "Version after: #{version}"

And here is the output from rake db:schema:load --trace

-- assume_migrated_upto_version(20100315153347)
Version Before: translator_20100315153347
Version after: 0

As you can see, db:schema:load is prepending my table prefix to the version number, and the version.to_i code can't handle that.
