This kind of error also happened:
1. Open an exist bug
2. Change the product in the product select list, then click the 'Save Changes button' immediately.

Comment 2 Jeff Fearn 🐞 2015-05-15 06:30:19 UTC

This is due to an rpc request being terminated on unloading the page. It might be possible to bind a function to the onbeforeunload event and set a flag to stop the message being displayed.
