Description Paul Rijnvos CLA 2020-11-05 04:28:06 EST 
This exception started to show up after attempts to provide a custom CSS/Theme from within Papyrus.
Very little dialogs regarding custom CSS/Theme seem to work.

After this Eclipse/Papyrus keeps reporting these runtime exceptions in an Exception-dialog.
