carrierwave-postgresql + carrierwave_backgrounder

[nfedyashev]

Has anyone succeeded in making carrierwave-postgresql and carrierwave_backgrounder working together?

process_in_background :image

causes the following exception:

no implicit conversion of nil into String

Without that carrierwave_backgrounder's option conversion works great for my model.
Perhaps anyone with deeper knowledge of carrierwave/carrierwave-postgresql/carrierwave_backgrounder can give me some advice?
