Siegmar, Ralph, I'm sorry to response so late since last week.
Ralph fixed the problem in r32459 and it was merged to v1.8 in r32474. But in v1.8 an additional custom patch is needed because the db/dstore source codes are different between trunk and v1.8. I'm preparing and testing the custom patch just now. Wait wait a minute please.
