Yeah, that are the handles and not the entries. Sorry that I was 
confused about that.

Your patch is correct, you should just update the commit message a bit.

BTW: Could you cleanup error handling here a bit more?

E.g. add an error_put_list handle and drop the "if (info)" and instead 
return directly if we fail to allocate info.

Thanks,
Christian.
