Stacktrace dumped when bravos sent without a message

[nitrocode]

Hi. I noticed a stacktrace was dumped when I sent bravos without a message. The bravos were removed from my balance and I'm unsure if the bravee received said bravos.

Maybe replace line 100 with this:

  if text.split(' ').length > 1
    msg = text.split(' ')[1...].join(' ')
  else
    msg = 'Bravo!'

Trace:
