Invoice in ZUGFeRD Extended format throws exception

[DasElias]

Hi,

I have tried to visualize the example invoices provided together with the ZUGFeRD standard. For the file "EXTENDED_Warenrechnung.pdf", Quba crashes with an exception:

However, since it is an example invoice provided by the authors of the standard, I doubt that this is an issue with the invoice. Moreover, some online validators revealed no issues with the invoice.
