update-mime(8) § DESKTOP ENTRIES

  In addition to the abovementioned mechanism update-mime also
  parses desktop entries in  /usr/share/applications/
  to  generate  mailcap  entries.  These entries are given
  a lower priority than those in /usr/lib/mime/packages.

It seems there are a couple of bugs in update-mime:

1. It does not perform an unquote pass that should retain only a half of 
backslashes from Exec field of .desktop file.
2. It does not skip x-scheme-handler/* entries. Are there applications 
that may use such entries?

Perhaps there is a bug in s-nail as well.
