The person sabotaging the match is Professor Quirrell, but Hermione sets fire to Professor Snape's cloak.
Hermione thinks that Professor Snape is sabotaging it (really he is trying to save Harry).
In the book, on her way to Snape, she knocks Quirrell over.
In the movie, as far as I remember, Snape knocks him over when trying to put out the fire.
The result remains the same for the movie or the book though--Hermione did not set fire to the cloak of the person who was sabotaging the broom.
