OK, thanks.  (I think clearing the entire cache of gstrings is too
radical: we don't necessarily remove all the fonts from all the
frames.)

Now the important question: should we install this on master or on the
release branch?  I believe the problem is not limited to 28.0.50, is
it?  OTOH, is this safe enough to install on emacs-27?
