Created attachment 155858 [details] Patch fixing the problem. With the default C locale on NetBSD, the fixappdata.py script as run in the build reports an error: UnicodeDecodeError: 'ascii' codec can't decode byte 0xd9 in position 305: ordinal not in range(128) Please apply the attached patch to give fileinput.input() an explicit encoding argument - this fixes the issue.
Thanks for the report. The Debian maintainer encountered the same issue, and I came up with the fix https://invent.kde.org/multimedia/kid3/-/commit/cdc47207d2807f47222e904e441f95a523724ed1 treating the file as binary, which is a bit more tolerant than your solution. Is this OK for you too? I am still wondering why this affects only fixappdata.py, but not fixdesktop.py, and if this is a feature or bug of Python 3.11 (the Debian maintainer made the conclusion that the Python update might be the cause).
Thanks for the information - the committed patch works for me.
