Probably this problem from the FAQ
http://sup.rubyforge.org/FAQ.txt

P: I get some error message from Rubymail about frozen strings when
   importing messages with attachments.
S: The current solution is to directly modify RubyMail.
  Change line 159 of   multipart.rb to:
     chunk = chunk[0..start]
   This is because RubyMail hasn''t been updated since like Ruby 1.8.2.
   Please bug Matt Lickey.
