Problem with Bash

When I open terminal, bash is complaining:

-bash: {rtf1ansiansicpg1252cocoartf1038cocoasubrtf360: command not found
-bash: /Users/lv/.profile: line 2: syntax error near unexpected token `}'
-bash: /Users/lv/.profile: line 2: `{\fonttbl\f0\fswiss\fcharset0 Helvetica;}'

I have found the .profile file, but have no idea how to edit it to get rid of this error. Any idea? what may be wrong?
