Thanks for the report. This appears to be a Cocoa system message, rather than anything Toga or Briefcase is generating. It won't be visible at runtime (it's only visible here because dev mode is exposing the system log). It's not unheard of for macOS apps to generate system log messages because of bugs in Cocoa itself. On that basis, I think we can close this as "can't fix".
