[RCU] Problem with address book

Hi all,

I'm having some trouble with the address book in RoundCube 0.6. I have been looking for the answer -of which I'm sure there already is- on different resources. The problem is as follows. Contacts which are not in a contactgroup are not displayed in the address book. At first I thought this was by design, but adding addresses for automatic display of inline images also stores contacts without a group. This resulted in a lot of double addresses in the contacts table of the database. Updating these contacts to be in a contactgroup revealed the addresses and the images are then shown without a warning. What should I do to fix this, or rather: where can I find the answer.

Best regards, Marcel
