The visual error in the bug is already filed at #488789 and might not be related to the crash. I can confirm the crashing, it is consistently reproducible on a fresh profile in current Neon. It doesn't seem like moving the applet is required, just clicking it while in Panel Configuration mode is enough. (Though moving also works, as it involves clicking the applet). It does open the widget explorer though, not the alternative widgets popup. The label popup in Show Panel Configuration does show "Show Alternatives..."
Can also reproduce the crash; re-titling for clarity. The visual issues aren't related to this.

Yep, looks like as of that, the bug is impossible to experience anymore.
