Ok,
it looks like you have some permission issues with /usr/share/icons folder.
You should not run screenlets with sudo permissions, that was only to see if there is permission problem.
Execute "sudo chmod 755 -R /usr/share/icons" in terminal, and then you should be able to run screenlets like before.
About "python -u", execute in terminal "python -h" and there you can read about -u parameter.
