Question:HazardRate does not work for convolution

Hello,

HazardRate seems not to work for a convolution - it always returns zero.

restart;
with(plots);
with(Statistics);
X1 := RandomVariable(Uniform(0, 1));
X2 := RandomVariable(Uniform(0, 1));
HazardRate(1/2*X1 + 1/2*X2, 0.4); #returns zero
plot(HazardRate(1/2*X1 + 1/2*X2, t), t = 0 .. 0.9, legend = "Hazard Rate"); #plots zero
#writing hazard rate explicitly works fine
plot(PDF(1/2*X1 + 1/2*X2, t)/(1 - CDF(1/2*X1 + 1/2*X2, t)), t = 0 .. 0.9, legend = "Hazard Rate explicitly");

Thank you!
