 > We fix the issue by ditching the csv reader, and simply read the file in
 > binary mode, manually partitionning the lines on the first comma.

 > Then, we use the binary-encoded (really, un-encoded) package names and
 > filenames as values and keys, respectively.

 > Finally, for each filename of package we need to print, we try to decode
 > them with the default s for the usser settings, but catch any decoding
 > exception and fallback to dumping the raw, binary values. in that case.

 > Thanks a lot to Arnout for the live help doing this patch. :-)
