Oops. I have no idea why I was running it as root (that's what comes of trying to replicate an error in a hurry I guess), but I went and changed the source file to an application and it works fine now. (It still won't automatically start the proxy though). Thanks a LOT for figuring that out.

This:

didn't show up again when I wasn't running as root.

However, I tried launching a non-executable file again, not as root this time, to address this issue:
"Trying to launch a non-executable shouldn't cause the control system to be disabled though.
I'll open a bug on this."
Here's the output again:

Hi Natalie,

Are you running Eclipse as root? I see the following:

Also, when you launch the job, it picks up the following location for
the workspace:

> path:           /root/workspace/Max
> cwd:            /root/workspace/Max

I'm also puzzled about this:

> name:           max.c

This seems to indicate you're trying to launch ' max.c', which is the
source file, as an application. I suspect this is where the
permission denied error is coming from. Trying to launch a non-
executable shouldn't cause the control system to be disabled though.
I'll open a bug on this.

Finally, there is this error from Eclipse:

This is probably not related, but I've never seen it before.

Greg
