I'm not sure I understand: is this related to this bug in some way?

Bug#71343 seems to describe a GUI frame (if not, what does the
window-manager have to do with it?).  While here we are talking about
TTY frames, right?  And killing frames is not involved in this bug
report, right?  Or what am I missing?
