Почему в Kubuntu с LXDE перестали работать некоторые комбинации клавиш и как это исправить (подозреваю pgAdmin)?

Внезапно перестали работать во всех программах (Firefox, leafpad, NetBeans) Ctrl+A, Ctrl+S, Ctrl+F. При этом Ctrl+C, Ctrl+V, Ctrl+U и Ctrl+Alt+T работают как обычно. Решил перезагрузить компьютер и, закрывая PgAdmin, получил ошибку. Перезагрузка не помогла, гугление этой ошибки тоже. Как исправить эту проблему?
ОС: Kubuntu 14.04 x32, ядро 3.13.0-32
DE: LXDE
pgAdmin 1.22.1

Ошибка:
