I have a positive function and I'm taking an integral from it. I don't get why Maple computes the integral over a bigger region but not over a subset of it! Here is the integral. Does anyone know what is going wrong?

int(15.91549431*abs(6.100147120*10^6/k[6]-2.027358424*10^6*(1.241833982*k[6]/T[1]+2.)/k[6]+2.002942410*10^6/T[1])*exp(-50.00000000*(1.241833982*k[6]/T[1]-1.5)^2)/(k[6]^2*T[1]^2), T[1] = -.5 .. 0, k[6] = -.5 .. 0, numeric)
