The LCL has a default exception handler, so that the application

That's what I was relying on. There's nothing the application can do if
a user has write-protected the configuration files, or if there's a disk
error while writing (I didn't think of a non existing .config/, because
I've always found it there, before the last episode).
So I was just happy with a system error, which in this case fails to show.
As an additional information:
in FormClose
ini := TIniFile.Create(BadAppConfigFileName);
try
ini.WriteWhatever(...
...
except
on E: Exception do Application.ShowException(E);
end;
shows the error only on the console, but no visual dialog.
While
on E: Exception do MessageDlg(E.Message,mtError,[mbOk],0);
shows a proper message dialog.
Maybe this discussion should be moved to Lazarus list?
