OpenNebula

When starting oned first time, with empty DB, there is a crash when oned.conf contains USER_HOOK on CREATE.
When USER_HOOK is commented in oned.conf, then there is no crash on first run and everything works OK, even when USER_HOOK ir readded.
It is probably related with initial oneadmin & serveradmin users addition on first time.
Backtrace is here:
