Though marked as fixed in buil 200809290201 (Sept 29) i just got this error in build 200810031942 (Oct 03).
Some causes for this assertion were fixed lately (a8e67ec3eec0). If you still get this assertion please try to reproduce with finer logging (-J-Dorg.openide.nodes.level=100). Thanks.

Maybe I should file another issue, but I got the same stacktrace in today's nightly build (200810150201). I was deleting a folder from a (versioned) entry in the Favorites window. After the exception, the popup menu on subfolders in favorites ony contains the "Add to Favorites..." item.
Is it reproducible? Please provide steps how to reproduce or attach log with finer logging for nodes and explorer (-J-Dorg.openide.nodes.level=100 -J-Dorg.openide.explorer.level=100)

New duplicate is caused by previously reported error: "java.lang.IllegalStateException: Some of a set of deleted nodes are not present in the original ones. See #15478; you may need to check that your Children.Keys keys are safely comparable."
