Thanks for the quick help. There was one single folder in the privacy options of spotlight, which I temporarily removed now. Actually no file at all is found (so I assume the reason it is not the metadata of a specific file), but I picked one of the files and here comes the output of your tool:
/Volumes/Macintosh_HD/Users/pollow/python.m
