[3dprinter-general] Bug#1121290: outdated in relation to python3-numpy

[Václav Ovsík]

Hi,
yes, the version 5.0.0-6 is not up-to-date for python3-numpy.

During click to Preview in Cura, never-ending slider slides and the following
error appears in the terminal:

    ValueError: The binary mode of fromstring is removed, use frombuffer instead

with a context:
