These are *all* over the place in various software, it can result in a huge amount of crap sent to syslog. Example from the first machine running GNOME I looked at below - if I look harder there's a good chance I'll find some with "last message repeated" counts in the hundreds. Basically it seems that g_debug callers expect to be able to use NULL srrings and it would be huge whack-a-mole to clean them up. I wonder if it might be better to do something to catch these in g_debug() and avoid passing the NULL to vfprintf.
