If needed, I can do a debug build and step through this, but I'd
rather not, if someone can identify the issue first.

So do you think this is related to the monitor-mode problem that Henri
also saw?

I suspect it is because the interface doesn't have an IPv4 address. Do
you have a "mon1" interface in ifconfig output also?
