Tipo complesso "servizio": il modello di contenuto non è deterministico

Question

Ho riscontrato questo strano errore con Symfony2. In localhost tutto funziona bene, ma quando provo nel mio server ottengo questo errore PHP:

[06-Mar-2013 22:04:50 UTC] PHP Fatal error: Uncaught exception 'Symfony\Component\DependencyInjection\Exception\InvalidArgumentException' with message '[ERROR 3070] complex type 'service': The content model is not determinist.

Sembra essere qualcosa su XMLFile Loader, ma ho fatto nessun cambiamento nel suo fascicolo

Questo è un bug in libxml2 - stai usando RHEL o CentOS? Scopri https://rhn.redhat.com/errata/RHBA-2013-0591.html e se non si può aspettare che l'aggiornamento per essere rilasciato attraverso yum update, allora è possibile tornare a una versione precedente:

yum downgrade libxml2-2.6.26-2.1.21.el5_9.1

grazie enorme a @denkiryokuhatsuden su questo GitHub issue per la correzione.
