StaleStateException while deleting an org

[Lukas Zapletal]

Hello,

got this regression in Katello when I create an org, import some 
certificates there and then delete the org.

The thing is it works fine on Fedoras, but it fails with this error on 
EL 6.1 (GOLD):

Test suite Provider import
----------------------------------------------
org create                              [ OK ]
provider create                         [ OK ]
provider import_manifest                [ OK ]
org delete                              [ FAILED ]
org delete --name=Import_Org_dccc6ba
RestClient::InternalServerError: Candlepin::Owner: 500 Internal Server 
Error {"displayMessage":"Runtime Error 
org.hibernate.StaleStateException: Batch update returned unexpected row 
count from update [0]; actual row count: 0; expected: 1 at 
org.hibernate.jdbc.Expectations$BasicExpectation.checkBatched:85"} 
(DELETE /candlepin/owners/Import_Org_dccc6ba)

Wild guess: Looks like Candlepin is still working on something after 
import while there's a request to delete the record -> bang .oOo. ?

Hints? Thanks...
