[news.eclipse.technology.albireo] Re: CTRL-C stack overflow

["James Peltzer" <canadianguy@xxxxxxxxx>]

Never mind.  As it turns out, it was an ID-10-T error.

The original RCP application I built on top of had an accelerator set for
'ctrl+x' to shutdown the application.  This was never removed and sat around
for a year before I noticed it.

Sorry to waste anyone's time.
