                      there appears only a blank mode-line, whereas in message buffer we read:

I tried installing the powerline package and then saying `M-x
powerline-center-theme' in the latest Emacs 28, and I got no errors.

Do you have a recipe to reproduce this problem, preferably starting from
"emacs -Q"?

I think this has been fixed with

  https://github.com/milkypostman/powerline/pull/185

which became

  commit cfff1cfe63793ea1a8bcfcae50c296558384cf08
  Author: Theophilos Giannakopoulos <theo <at> abstractnonsense.org>
  Date:   Tue Mar 16 21:10:53 2021 -0400
  
      Change :scale arugment from t to 1 (#185)
      
      * Change :scale arugment from t to 1
      
      t is no longer accepted as :scale argument for create-image, but using 1
      has the same behavior as before.
      
      Fixes #184.
      
      * Change other uses of :scale from t to 1

No further comments within 2 weeks, so I'm assuming that this has been
fixed.  I'm therefore closing this bug report.

If this conclusion is incorrect and this is still an issue, please reply
to this email (use "Reply to all" in your email client) and we can
reopen the bug report.
