Question:Re / Im with dirac not working ??

I use Maple 15 and I want to take the real and the imaginary part of a simple expression e.g. 5*Dirac(x)+3*I, having already assumed x a real value. However, Maple seems to have problem with the Dirac function. The output looks like this:

> assume(x, 'real');
> Re(5*Dirac(x)+3*I);
                         5 Re(Dirac(x))
> Im(5*Dirac(x)+3*I);
                       3 + 5 Im(Dirac(x))
 
Any thoughts on how to overcome this are welcomed.
