debugging with gdb
Program received signal SIGSEGV, Segmentation fault.

(gdb) quit

I can reproduce this SIGSEGV with [email protected] experiment.
Default, it uses vle.output and file plug-in for views. If I switch
manually to storage, all is done.

These is an error in pyvle.cpp

    res = sim.run(new vpz::Vpz(*file), man, th, 0,1, &error);

    if (error.code != 0) {
        std::string filename = utils::Trace::getLogFilename("pyvle.log");
        std::ofstream* logfile = new std::ofstream(filename.c_str());
        (*logfile) << _("Error in pyvle_manager_thread: ")
                        << error.message
                        << "\n\n" << std::flush;
        logfile->close();
        return PyString_FromString(error.message.c_str());
    }
    resPython = pyvle_convert_simulation_dataframe(*res);

    delete res;
    return resPython;

*res and delete res can SIGSEGV if sim.run returns NULL.
