I am attaching this new log because the same bug appear to be cause by a different segment fault (before in _eeschema.kiface, in this on libthread_db.so.1).

Starting program: /usr/bin/eeschema 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
