If waitForStarted() failed, it means one of two system calls failed:
Check whether you passed the correct path to QProcess. That's basically the
only thing that can cause a process to fail to start. Check the errorString()
If that isn't the case, run your application under strace -ff and check at the
beginning of the second file what it tried to do and failed.
