You have found a good buglet here.  Basically the 
plugin/insert/send management code does some complicated stuff to 
automatically manage the channel counts within a track/bus. 
You've found a case that the code overlooks.  Arguably sends 
shouldn't affect the number of internal channel streams that 
follow it (like plugins or inserts should).  Please enter the 
excellent description into a bug in the bug tracking page 

In the meantime, Mark's workaround idea sounds promising...
