Yes, that's right. The tags must be in the tag table for the buffer. 
However we could use a better error message in this case... a bugzilla
report suggesting that would be good.

Well, you can share the same tag table between two buffers;
gtk_text_buffer_new() accepts a tag table argument. If two buffers
have the same tags you'll also save a bit of memory this way.

If you want some of the same tags but not all, then you need to 
create two identical tags. Conceivably we should have
gtk_text_tag_copy(), but lacking that you can easily just have a
function that creates the tags, and call that function twice.
