Please communicate to the user any failure in the Nautilus extension
- lack of automated QA for this feature: requested autopkgtests in Debian on https://bugs.debian.org/858204, upstream tests would be welcome as well but that's not what this ticket is about
- lack of manual QA for this feature: I'll ignore this for now, hoping that automated QA is implemented soon enough; if this doesn't happen we should probably consider documenting a manual test suite in our release process doc
- developers not testing the code they just refactored: I don't think we can do much about this, except learning from this sad experience
nautilus/nautilus-mat.pybeing overly self-confident, and thus not robust enough in face of programming errors => silently failing
This ticket is about the last of these root causes: perhaps
menu_activate_cb should wrap all its code in a try/catch block, and display an error dialog to the user if any unhandled exception is raised.
