-------------------------------------

Thanks a lot Bill, I reproduced the same problem with the far easier test case I'm pasting below. I'm investigating this issue and I'll keep you updated. 

{code}
    @Test
    public void testNotWithBreakingBranch() throws Exception {
        // DROOLS-1068
        String drl =
                "rule R when\n" +
                "  Integer()\n" +
                "  if (true) break[branch]\n" +
                "  not Integer()\n" +
                "then\n" +
                "  System.out.println(\"main\");\n" +
                "then[branch]\n" +
                "  System.out.println(\"branch\");\n" +
                "end\n";

        KieSession ksession = new KieHelper().addContent( drl, ResourceType.DRL )
                                             .build()
                                             .newKieSession();

        FactHandle fh = ksession.insert(1);
        ksession.fireAllRules();
        ksession.delete(fh);
        ksession.fireAllRules();
    }
{code}
