I have no idea why new_password seems to be NULL in:
  if (!g_output_stream_write_all (reply_stream,
                                  new_password, strlen (new_password),

This would mean either gnome-keyring or the password dialog returned success but a NULL password, which doesn't seem possible.

I'm adding a check to avoid the crash which spews a warning in this case. Hopefully this can give us information from people seeing this.

It is an old bug. It looks like it was solved by Bug 608510. If you still see the problem, please reopen.
