Fourier transform : failure with hyperbolic secant and log argument

Hi all,

Does someone know why Mathematica succeeds in findind the fourier transform of Sech[x*a] but not of Sech[x*Log[2]], and why does it return a result in terms of gamma functions with Sech[x*Log[2.0]] ??

I know this is not really an issue since I can replace Log[2] by the symbol a, but it worries me about mathematica's reliability.

Thanks.
