Tvheadend

Hi all.
I've been using Tvheadend from over 2 years under Ubuntu (Debian) and it worked like a charm.
But now I have to face the problem of using it under Fedora Core 7 (it is hardware driver dependence - I cannot use more recent system).
I downloaded and successfully compiled version 3.2.18~g40a8920 (configurer complained on missing zlib anyway).
When I launch it from console and try to access locally for the first time - I am able to access web GUI.
But for the second (and more) time it freezes on "Transferring data from localhost".
Sometimes console shows following error:
[ERROR]:HTTP: 127.0.0.1: /extjs.html -- 401

I never got to remote access from other machine in local network (I stop iptables before trying it).
It always freezes on "Transferring data ...".
Sometimes console shows following error:
[ERROR]:HTTP: 192.168.3.2: /static/app/tvheadend.js -- 500

This situation happens no matter which user launches Tvheadend (I use root and created hts account).
I also couldn't associate this behaviour with missing or present -C launch option.
