argus-server, ra utility filter problem on amd64 arch

[Boot User]

Hello!

Have a Ubuntu:
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty

Linux 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64
x86_64 x86_64 GNU/Linux.

Also, have installed argus-server package:
ii argus-client 2.0.6.fixes.1-3 amd64 IP network transaction auditing tool
ii argus-server 1:2.0.6.fixes.1-16.3 amd64 IP network transaction auditing
tool

When trying get info about some host, ra utility find nothing:
#ra -r argus.log - host 1.1.1.1
#ra -r argus.log show all information, but when filter, have nothing.

When try to run such utility on i386 arch, I get result as expected.

Is this bug in ra utility filter?
