Answering to myself: g_test_init() always makes warnings and criticals
fatal [1]. A proper way to change this behaviour would be to use
g_test_log_set_fatal_handler() to install a new handler that ignores
log messages coming from the library domain: this works fine but pull
in a glib-2.22 dependency.

I ended up using g_log_set_always_fatal(0) instead, forcibly
disabling any fatal flag (apart g_error() ones, fatal by design).
