Logging to stdout create a logging error and infinite loop

[DivingDuck]

          That one is working fine now, but found another one:

I got an logging error when Log to console is activated. I did a connect and disconnect. When I then try to close the Pronterface Window I'm not able to do so and got the second traceback w/o been able to close Pronterface. I need to kill the process manually. Maybe also a path problem with dirs as I can't see any update in the log file.

Edit: I forgot to mention that the errors happen only if I run from the binary file - running from source is fine.

Terminal output:

Verbinde...

During handling of the above exception, another exception occurred:

... I'm not sure that I had test this exact combination. The error only happen when I switch from not logging to stdout to logging to stdout and then restart Pronterface and there only if I run from binaries. Running from source is fine and do not show the behavior.

I need to take a closer look what happen with introducing this change (https://github.com/kliment/Printrun/pull/1473) and why it fails in such a strange way and more over why there is no entry with the error in the log file as well...

@neofelis2X,

Can you please check this as well for macOS binaries? I want to know if this is only related to the Windows binaries. Running from source do not create this issue

Test procedure:

1. Start the actual development binary.
2. Activate via -->Settings -->Options -->User Interface Log to console and close the Window with ok.
3. Close and then restart Pronterface again
4. Connect to a printer and then disconnect.
5. Try to close Pronterface

Thanks in advanced.

Okay, i followed your instructions, made a binary from master, set log to console etc, also startet it --verbose to see if there are any extra messages. But no errors. Connects, printer moves, disconnects, pronterface closes without any complaints. Everything very normal.

Thanks for testing. So it seems like this is a Windows only issue.
