[Qucs-help] EDD problem

I have a small problem with the EDD part, more an irritation than an
show stopper.
 
I have created an arbitrary voltage source using an EDD followed by
current controlled voltage source, the output from this source, and
others, then acts as an input to a further EDD.  The problem is that
during DC simulation the input to 2nd EDD is always treated as zero even
if an initial condition is defined leading to divide by zero errors in
some equations.
 
The work round is simple, just add a small fixed value to the relevant
terms so as I said an irritation rather than major problem
