TMail very large attachment handling

gistfile1.rb

# TMail was crashing trying to process very large messages in a regexp
# match to check to see if the message body is UTF-8 or something
# crazy like ShiftJIS or some other Japanese thing.  Let's just go
# ahead and assume that we're always dealing with UTF8 messages to fix
# the crash.
#
# This will probably break lots of other things. I am going straight
# to hell for this.
