マルチスレッドのqt webkitアプリケーションで発生したsegfaultをデバッグしようとしています。gdbできれいに印刷する目的でpython-dbgをインストールしましたが、起動時に次のエラーが発生しました
python2.7-dbg node.py

msgpack を使用しないバージョンのスクリプトを実行すると、同じ結果が得られます...

どちらの場合も、Py_InitModule4 を探しています... Python の専門家のアイデアはありますか? コードは通常の python 2.7 で正常に実行されます (セグメンテーション違反を除く)。
gdb できれいに印刷する簡単な方法があれば、それも受け入れます。基本的にはPythonスタイルのスタックトレースを探しているだけです
