In any case, I tried with your XPOI.INI file (so the settings would be exactly the same), and placed the airplane at EDTF, with the geonames points enabled, and waited for several minutes, but no crash that I could see, even after turning on/off the points several times.
Other than being sure you use the current version of XPOI (which also downloads the very latest Couatl, which you have already, as seen in your Log file), I don't know what else you can try, since I cannot reproduce your problem.
If you remove all the %APPDATA%\Virtuali folder, and reinstall XPOI and GSX, all your settings will be removed, so it's like a clean reinstall. Note that, if you do that, you'll lose all your GSX scenery and airplane customizations so, if you made some, you might want to MOVE that folder somewhere else, instead of removing it.
