You max remove the stderr=open(os.devnull, "w") and see what's printed on the console. > Furthermore, I wanted to correct the vignetting test images in > DigiKam using the generated .xml but the program refuses to load > the .xml when I place it in either /usr/share/lensfun or > /usr/local.share/lensfun/update_1. What is the error message?

But a failing autodetection should also fail before your changes.
