    cmake -DCMAKE_DISABLE_FIND_PACKAGE_Python3Interp=TRUE -DCMAKE_BUILD_TYPE=DEBUG ..
  2. Start relex by running opencog-server.sh
  3. Start cogserver using the following configuration file, load-opencog.txt (.txt extenstion is used for loading to github) 
    gdb -ex r --args guile -l load-opencog.txt
  4. Load ghost rules 
    cd /loving-ai-ghost/bin 
bash run.sh
  5. From the terminal where the cogserver is started, interact with the bot until it segfaults

Screenshots!? One can't control-F in a browser to search it. And google cannot index the contents.

Anyway, opencog/atomspace#1976 should "hide" this bug. There is still some bug in the diffusion agent, because it is sending the atomspace some atoms that are not in any atomspace.

It would be easiest to fix the diffusion agents before installing the fix opencog/atomspace#1976

Also, it would be best if the diffusion agents got some unit tests, to verify that they work correctly.
