[Edit]
Will return sqrt(pi)*exp(-t^2/4)

In fact, with the latest stable version (13441), I got for
∫(e^(-x^2-i*t*x),x,-∞,∞)
the following results:

Real mode (for the variables):
the message "No check were made for singular points of antiderivative sort(pi)*e^(-1/4*t^2)/2*erf(taylorx7-(-i)*t/2) for definite integration in [-infinity,infinity]
Then the result: 0

Complex mode (for the variables)
a long message "Warning, complex variables is set this can lead to ETC ETC"
Then the result: undef

In any case I do not get the correct Gaussian function. The same problem happens with both the calculator and the Android emulator.
