Comment 20 for bug 808007

I can't prove that all instances of this fault have the same cause, but there is an issue that the shift switcher exposes when right click is processed.

There's a fix committed by Łukasz to the shift switcher to remove an unused "Terminate" option, and I'm working on core to prevent plugins that expose options that don't exist causing a crash.

If you see this problem with other plugins let me know.
