[Bug 1053749] Re: UnicodeDecodeError from broken package descriptions

[Derek]

adamski99 - you can use the various iconv commands in the comments to
locate the problematic line in your file, then edit it.  You'd probably
want to mention the package here, too.

Personally, it was davmail.  Thanks for the fix.
