Magic PtokaX behavior on Settings.xml file with XML syntax errors

I've spent rather long time to dig out following problem:
PtokaX silently loads default settings without notifying user, if Settings.xml could not be loaded by tinyXML library.
But this appears as some kind of magic to user:

When I start PtokaX (v5.0.1 or SVN latest), it says 'Server start failed', and system.log contains message like
Tue 24 Dec 2013 10:52:02 AM MSK - Resolving of hostname '<Enter hub address here>' has failed.

I looked to Settings.xml - there was specified a valid IP address. I've checked network settings - all was pretty good, but where is the problem?
Only strace and looking through the sources helped me to find out the problem:


Code: cpp
    if(doc.LoadFile()) {
        TiXmlHandle cfg(&doc);
       // XML reading 
    // else DO NOTHING!

Here should be some diagnostics using methods
doc.ErrorDesc(), ErrorRow(), doc.ErrorColumn()

And I think server should NOT start if settings file is syntactically incorrect.
