Villa, who remain unbeaten after five draws and one win from their opening six matches, looked set for fifth place in the table as they led through a controversial penalty from midfielder Barry Bannan.
Referee Michael Oliver ruled Armand Traore pulled Gabriel Agbonlahor's shirt in the 58th minute. Traore's misery was completed after 90 minutes when he was sent off for a second bookable offence.
That seemed to set the seal for Villa's victory but a minute later a QPR break ended with Villa’s Stephen Warnock deflecting Heidar Helguson's cross on to Dunne's knees and he could not stop the ball crossing his own line for his ninth Premier League own goal.
