I can't *really* help you, but I might be able to.

After all I'm not a Roundcube developer...

I can try and suggest where the culprit may lay; you need to raise the 
issue with the Roundcube developers in order to get it resolved though.

If it is only this one user the issue is occurring with, I suggest you 
destroy all cache table records associated with the user, and check 
whether his preferences accidentally list his one MySQL address book
