I tried switching to breeze on Ubuntu, but I'm still not able to
reproduce the problem.

The bug report over at the Gnome site says:

----
Emacs Is using system-file-manager (an app icon) which is wrong, so, it's an 
emacs bug not a Breeze bug. If that button is to open the file manager it could 
use some other action icon.

Adding the icon for this bug, will in turn, bring back the bug where the task 
manager plasmoid used mono icons.

Please report it to the emacs devs.
----

So I guess we should just fix that?  It's 

    ("etc/images/diropen" . "n:system-file-manager")

in x-win.el and pgtk-win.el that's the culprit, I guess?  Anybody have a
suggestion of a more appropriate icon to use?

(Since I can't reproduce the problem myself, I can't really test.)
