The process definition allows a None state but the build_call_graph utils function intended for creating printable output of the call graph does crash in this case. A None state indicates some undefined behavior in the code, but the application should not fail because of the formatting of the output. This commit makes build_call_graph handle None states. Partial fix for #6585.
