I'm experiencing a consistent crash in the following scenario:

1. Open MacGDBp. By default de "Attached" checkbox appears checked.

2. Uncheck that box. Wait a few seconds.

3. The app crashes with the following info:

Is this while you're attached to a debugging session?

Thank you for your bug report. This issue has been closed and fixed in git. This change will be available in a future release, but you can download the change at any time from the git repository, found at http://www.bluestatic.org/git/.

No, I'm not attached to a debugging session. I'm just launching the app.

But it's an interesting question. So I did this:

1. Launched MacGDBp
2. loaded a page of a web app, to start the debug session, all good, I see the values of various variables
3. hit the stop button in MacGDBp
4. uncheck the attached checkbox
5. check it again - a "Could not open socket" message appears in red in the status bar of MacGDBp
6. toggle between checked/unchecked at will, no more crashes
7. closed MacGDBp
8. started it again, now the "Attached" box appears unchecked (as it were when I closed the app)
9. check it
10.uncheck it => BOOM crashes again.

I ran a similar scenario by not involving the stop button too. It seems that the bug happens only when there is no debug session started

Yup. I needed to add a NULL-check. Fix was a two-liner and will be included in the next maintenance release (probably in a few weeks).
