popt warning

[Elan Ruusamäe]

sometimes i see such message when building packages:

warning: existing POPT configuration file 
"/usr/lib/rpm/rpmpopt:/usr/lib/rpm/%{_target}/rpmpopt:/etc/rpm/rpmpopt.*:/etc/rpm/rpm
popt:/etc/rpm/%{_target}/rpmpopt:~/.rpmpopt" considered INSECURE -- not 
loaded

not always, i.e building same package i sometimes see this and sometimes 
do not.
rpm-5.4.15-31.x86_64

any ideas what this is about?
and it appeared rather recently...
