Octave.app log: "Path given to -[NSWorkspace iconForFile:] is not a full path."

Hello,

I just downloaded Octave.app 6.2.0 (for mac) on macOS Big Sur 11.2.3 and
every time octave-gui window gains or loses focuses, I see the log "Path
 given to -[NSWorkspace iconForFile:] is not a full path." which is pretty
disruptive and ends up filling the command window pretty quickly.

I saw reference to this log on this Github issue (
https://github.com/octave-app/octave-app/issues/80) and apjanke suggested I
share it with the mailing list to see if it's perhaps a wider problem for
Mac users.

Best,
Alex
