creation of launching-images with generate-launching-images not possible

[Tabaluga]

Dear @KALEL1981,

Thank you for your great Super Retroboy Theme.

Unfortunately, the creation of launching-images for each system with the generate-launching-images script is not possible.

The error message is that the theme.xml file is corrupt.

Is there a possibility that you can fix this error?

Thank you very much.

Best regards
