In addition, looking through the stack:

#2  0x08351f4d in boost::_bi::list1<boost::_bi::value<MetaContractPres*> 
 >::operator()<boost::_mfi::mf0<void, MetaContractPres>, 
boost::_bi::list1<MetaContract*&> > (this=0x8587c28, f=@0x8587c20, 
a=@0x8046104)
     at /opt/app/boost_1_32_0/include/boost-1_32/boost/bind.hpp:228
228             unwrap(&f, 0)(a[a1_]);
(gdb) p f
$3 = (mf0<void,MetaContractPres> &) @0x8587c20: {f_ = {__pfn = invalid 
pointer to member function

The destructor for MetaContractPres is called, the destructor for it's 
base class trackable is called.  I can't tell why the signal is not 
disconnecting (otherwise you'd have the example program by now :)

Everything works fine if I disconnect from all signals manually.  Is it 
possible that some of the trackable's connections aren't controlling??
