Version: 2.1 (using Devel) Installed from: Compiled sources OS: Linux Sometimes sending Ctrl+C to a konsole window doesn't actually seem to send an interrupt. I can't always reproduce this but it does seem to happen during cmake builds a lot. I've also seen it when I kill kwin, then start it from the command line...I can't Ctrl+C to kill it again.
