[Debian-med-packaging] Bug#779655: invesalius: "ZeroDivisionError: float division by zero" upon importing DICOM X-ray videos

[Axel Beckert]

Package: invesalius
Version: 3.0~b5-4
Severity: normal

Hi,

thanks for packaging software for Debian which enables me to view my own
medical data on my own and Debian running computer! :-)

I've tried to view some X-ray videos in DICOM format with Invesalius and
when I want to import them it shows me that there 8 videos (or images,
not 100% sure) to import, but as soon as I click on the "Import" button,
I get an empty (0%) progress bar popup and the following Python
stacktrace on the commandline where I started Invesalius:

Traceback (most recent call last):

ZeroDivisionError: float division by zero

(I could import and view my computer tomography data without issues into
Invesalius, so it's not a general issue, maybe just with some specific
data formats or even with some specific data.)
