Hi Yaroslav, This seems to be the effect of a restrictive umask (0077, specifically) to user root, either through explicitly setting it at your startup files, or through pam settings.
Dhelp code does not set permissions for the created files, rather assumes the customary 0022 umask for user root. There is a *lot* of code out there that does this assumption, so I would not consider this a bug. Although it is quite some time since the original report, if you could confirm whether that was the case then it would be useful. regards George
