Subject: bug#4835: 23.1;Improper `Invalid face reference' messages. Performance degraded.
Date: Mon, 9 Nov 2009 15:44:24 -0800

Any news on this?

> In any case, _this_ bug is about the `Invalid face reference' 
> messages and performance degradation. I get those messages
> even when using a symbol function, so this bug is not fixed
> by simply adding a restriction to symbols.

> If I'm mistaken and have missed something, please advise. I

> IOW, for Emacs generally, I agree with you that "it would be

> But my concern now is the `Invalid face reference' messages.
> I corrected the code to use a symbol, not a lambda, but the
> problem remains.
