Endless debugger loop when attaching to unstarted application that produces ptrace error

Steps to reproduce:

1. Attach to unstarted application
2. Check "Reopen dialog when application finishes"
3. Run the application from Creator
4. A "ptrace: Operation not permitted." error is displayed (QTCREATORBUG-3509)

The last step will keep happening, all the while it seems like Creator tries to re-run and hence attach to the application?

What this means in practical terms is that the computer has to be shut down forcefully as the message dialog takes focus whenever you try to open e.g. a terminal to kill Creator.

Creator should detect that bad things are happening in a loop and prevent it from continuing.
