QProcess and firefox

Question

I have an issues trying to launch firefox through QProcess. Here is the function I used to launch commands (such as firefox, mkdir, ...)

double launch_nowait(string cmd, bool display) {
    string command_name = "";
    string command_param = "";
    bool first_space = false;
    for (int p = 0; p < cmd.size(); p++) {
        if (!first_space && cmd[p] == ' ') first_space = true;
        else {
            if (!first_space)   command_name += cmd[p];
            else                command_param += cmd[p];
        }
    }
    cout << "NOWAIT [" << command_name << "][" << command_param << "]" << endl;
    QProcess* process;
    //process->setWorkingDirectory(".");
    //process->waitForFinished();
    process->start(QString::fromStdString(command_name), QStringList() << QString::fromStdString(command_param));
    return 0;
}

I tried several things such as :

• removing parameters,
• changing the navigator to chrome
• adding a wait
• setting the working directory

But it always ends with a seg fault.

The strange thing is that when I use this function to create a directory it works fine.

Thanks for your help,
