It does indeed expect this. Aravis also started printing the camera name at the top of the genicam file which is not very helpful, so you should remove the line:

Basler-21630837

and replace it with:

<?xml version="1.0" encoding="utf-8"?>

I should really fix the script to be robust to this...

Thanks,
Tom Cobb
