Profile2 loses field data when reverted with "drush features-revert {featurename} --force"

I posted this on http://drupal.org/node/1316874#comment-5705822 but I think it is a different issue than that of the original poster.

The issue is that reverting a feature containing a profile2 profile results in existing data being wiped.

I have just tested this on a vanilla D7 install with the following versions:

Drupal 7.12
Profile2: 7.x-1.2
Features: 7.x-1.0-beta6
Entity: 7.x-1.0-rc1

Here's the setup:
We have profile2 profile set up with a number of fields.
We export the profile as a feature and use this to deploy the profile2 configuration.
Reverting the feature via drush with force
drush fr {featurename} --force
results in all profile2 field data disappearing.

When prompted:
Do you really want to revert profile2_type?
Answering 'no', keeps the data. Answering 'yes' loses the data.

Steps to repeat:

• Add fields to default profile2 entity.
• Add data to these fields on a given user account.
• Export profile to a feature, confirm feature is enabled and at default state.
• Revert feature using drush :
• drush revert {featurename} --force
• Review data in user profile - profile fields are now empty.

I'll do some more digging to see if I can find why this is happening, but if anyone else has any ideas, I'm all ears.
