I am not sure, maybe this is because I deleted some feeds from the list (did some minor feed list restructuring).

How to reproduce: - Create a folder "foobar". - Import a feed from some website. - Move feed from "imported folder" to "foobar" - Delete "foobar" (and the added feed with it) - Exit Akregator => Crash Something goes wrong tracking the displayed nodes. It seems it has to do with moving nodes and deleting the later. |
