IAE: Listener ScoutSigns (ScoutSignsDetailsDialog) was not registered before or already removed

[sa.se.noble@…]

What steps will reproduce the problem?

1. Close the open JOSM session, thus prompting me to save, upload etc.
2. Choose to save session to hard disk (do NOT upload)
3. USe on screen prompts to save session

What is the expected result?

The expected result is for the application to save the current session to hard disk, which it is doing, then close the program.

What happens instead?

The session is saved to my local hard disk but the program continues to run, it does not accept any input. I can however click the X at the top of the window manager which will close the program.

Please provide any additional information below. Attach a screenshot if possible.

Java client and JOSM application should be, to the best of my knowledge, running under default conditions. Thusly, I am unsure of what information may be of more use.
