MongoMapper - can't modify frozen object on destroy

[motdotla]

Jonas, great upload gem. I really like it - was super easy to get started with. Thank you.

I am getting one error related to using it with mongomapper, but I realize you just added this support.

The error is 'Type error: can't modify frozen object' when doing User.destroy_all or User.first.destroy, etc. The error is only on destroy and the user actually gets destroyed, but tests fail because of the ugly error.

Following is the stacktrace with the rspec test I'm running. I had the same issues when running in merb -i -e test|development

I do not get the same error if I delete by doing: User.delete(@u.id) or User.delete_all

Possibly, it's related to MongoMapper's destroy method in lib/document.rb lines 302-308?:
def destroy
return false if frozen?

    criteria = FinderOptions.to_mongo_criteria(:_id => id)
    collection.remove(criteria) unless new?
    freeze
  end

Sorry about that, MongoMapper support is still a bit experimental.

I can't seem to replicate this error, could you try writing a failing spec?

Ok, I've forked and updated with the failing test. It's at:

http://github.com/scottmotte/carrierwave/tree/master

I'll send a pull request too.
