EINA_LOG_ERR() will assume EINA_LOG_DOMAIN_GLOBAL, so you're code is
not correct, you should either use EINA_LOG_ERR("bla") or
EINA_LOG_DOM_ERR(EINA_LOG_DOMAIN_GLOBAL, "bla").
We should have one domain per-submodule (or at least one domain
exclusive for eina), the more fine grained, the better to debug.
