Not a showstopper.

Attachment file sizes (at least in some cases) seem to be *way* off, for example:

    [ Part 2, Application/X-RPM  5.7MB. ]
    [ Cannot display this part. Press "V" then "S" to save in a file. ]

Hit V

   1     20 lines   Text/PLAIN                                                      
   2    4.3 MB      Application/X-RPM                                               

after saving:

$ ls -la sdr-3.0-1.src.rpm 
-rw-rw-r--    1 pekkas   pekkas    4207876 Feb 22 23:29 sdr-3.0-1.src.rpm

also happened with 4.31, at least.

Might this have something to do with the encoding used (and calculating the space needed by the encoded text,
rather than the saved file)
