bug#5891: [Aquamacs-bugs] Re: (no subject)

[Richard Stallman]

    With C-x d I opened a directory with TeX sources etc. I sorted by time 
    and saw a missfont.log file. I opened it with v, read its contents, 

At this point, if you switch back to the dired buffer, has its font
changed already?

Can you provide us with a complete self-contained test case?
