title: ddd hangs on start
body: <p>Question has been asked before and I see bug report on ddd newsgroups but none of the suggested solutions work for me. </p>
  
  <p>It comes up but when you try doing anything like opening a file it hangs with the message "waiting until GDB gets ready."</p>
  
  <p>A crucial fact, reported by others too, is that it works fine for some users and not others. I've compared the environments and can't find any significant differences. Any suggestions will be most appreciated.</p>
