I've been trying to dig deeper into this (guessing that
g_log_set_fatal_mask may have become a macro or something) and find
that I can call it after gtk_init_check() from within the program
without a compile time error, but the program still does not stop on
errors.

Indeed

g_print ("Error level was %x\n", g_log_set_fatal_mask (NULL, -1));
g_print ("Error level now %x\n", g_log_set_fatal_mask (NULL, -1));

prints out 0x5 as the initial setting of the mask and 0xfffffffd
 as the setting after setting to -1

but I then can trigger a slew of 

(denemo:1717): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion
'size >= 0' failed in GtkScrollbar

errors without the program stopping.

Is there something involving threads here?
