Note: you can use xfontsel to find out what fonts are available on your
system.
It's possible that what it should have been was
-*-courier-*-*-*-*-12-*-*-*-*-*-*-*. If you're willing to risk
ambiguity, you can abbreviate it. On my system, xlsfonts
"*courier*12-*" lists the same 8 fonts as the full specification.
However, the font specification can't be abbreviated to courier*12.

That's coming from an X toolkit, most likely Xt. You've got a resource
set someplace that is referencing this font and that font isn't available
or there is some other problem with it.
You can issue:
xrdb -query
to see what resources are in your resource database. Chances are this
font name is used to set one of the resources. The resource name would be
a big clue. But in general, you then would have to hunt around for the
place/file that is setting the resource, and that can be tricky because it
could be in any one of a number of places. There could be system-wide
resource files, application-specific resource files, and your own
resource files. If the resource is in a place that you can't change (or
find), then you could try setting it yourself, overriding it, in your own
resources to a value that works. That should get rid of the message.
