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

[Andreas Tille]

Hi Axel,

thanks for your bug report.  I hope you are fine and do not need to
diagnose your own. ;-)  I have put Thiago in  CC (in case he might have
missed the bug report).  He has close connection to upstream and will
surely work on fixing the issue.

As an independant hint you might like to try ginkgocadx, amide and
aeskulap (in this order) to perhaps see what you want to see.  Any
reports about these would be welcome as well.

Kind regards

     Andreas.
