Can't reproduce, so we need a crash log. See

Apparently no backtrace is created:

Similarly, valgrind doesn't appear to show anything:

I guess it's possible that spectacle disappearing when the Copy to Clipboard
button is click is how it's supposed to work? However, nothing is copied to the
clipboard.

Probably linked to bug 400479, which looks like a driver issue with Nvidia.

Do you have the "Quit after save or copy" checkbox checked?

Hmm, yes I do. So, no crash, but no copy as well. Any way to test if it is
actually performing the copy action?

Aha! Spectacle isn't crashing, it's just that the copy to clipboard
functionality doesn't actually work if spectacle is configured to quit
afterwards.

There's a patch that fixes this (https://phabricator.kde.org/D9117), but it got
derailed a while back. I'll see if I can resurrect it...
