Sorry about the delay.

Initial conditions work.  The problem with this circuit is that you 
have uncovered a bug with multiply coupled inductors.  This is a real 
known bug. Thanks for providing a circuit that demonstrates it.


Another comment. ..

With Gnucap, it is not necessary or desirable to insert voltage 
sources as current probes.  All devices will tell you their current 
if you ask.  For example:  IE(Q1) is the emitter current of Q1.  
Actually, there are lots of probes available.  If the one you need is 
missing, it is easy to add, and if you tell me I can add it to the 
official version.
