Sorry for all the posts. Reporting as observed, otherwise will forget later.
Search like 'sce-import game' for dCore Jessie results in 39 hits, pressing (n)ext proceeds to the next screen. Upon the last screen the (n)ext option is still present, so pressing (n)ext again doesn't crash just redraws last screen. User would not expect to see a (n)ext on the last screen. Similar situation on the first screen, the (p)revious option is present. Selecting (p)revious doen't crash, just redraws.
Minor but probably a lot of effort to fix, just reporting. Thanks.
