Is the asymptotic expansion of DawsonF[x] correct?

Hi,

When using Mathematica 10, the command

Series[DawsonF[x],{x,Infinity,6}]

produces a result involving a term i*Sqrt[Pi], which is hard to understand, since no such term should be present if x is real. Is this correct, or there is some bug in Mathematica 10?
