CUPS: Internal Server Error 500 (Kubuntu 10.04)

Kurcze, chyba tu

Od jakiegoś czasu mam problem z CUPSem. Każda próba wejścia do Administracji panelu CUPS dostępnego pod localhost:631 kończy się wywaleniem: Internal Server Error 500 (tyle, nic więcej) lub po prostu wyświetleniem cyfry 500.
Ostatni błąd w /var/log/cups/error.log wygląda tak:

Kod: Zaznacz cały

PID 10320 (/usr/lib/cups/cgi-bin/admin.cgi) crashed on signal 6!

Szukając w necie znalazłem różne informacje nt. "signal 9", ale raczej nie "signal 6".
Obecnie w systemie mam 3 drukarki: Samsung ML-1510 (zainstalowała się sama), Brother DCP115 (instalowana wg opisu na stronie Brothera; niejednokrotnie w ten sam sposób, zawsze działała) oraz PDF (za który odpowiada cups-pdf).
CUPS w wersji 1.4.2, dystrybucyjny z *buntu 10.04, system - właśnie ten.
Oczywiście błąd uniemożliwia drukowanie czegokolwiek, jak również administrację nimi przez www a także w innych narzędziach do konfiguracji drukarek.
Oczywiście też, kiedyś drukarki działały bez problemów.

Odświeżenie tematu.

To jeszcze naprowadzę. Istnieje pewne prawdopodobieństwo, że błąd nie leży w CUPS, a w apparmor, który nie dopuszcza CUPSa (w jego ostatniej wersji nastąpiły pewne zmiany, za którymi - jak się wydaje nie nadąża apparmor) do możliwości wpisywania w /dev/shn. Problem w tym, że zmiany, które są sugerowane dokonałem, a problem dalej pozostał.
EDIT:
OK. Zatem treść /var/log/cups/error.log

Kod: Zaznacz cały

Z powyższego najistotniejsze wydają się być dwie informacje:

Kod: Zaznacz cały

printer-state-message="P2POutputStream: write  error"

oraz:

Kod: Zaznacz cały

(/usr/lib/cups/cgi-bin/admin.cgi) crashed on signal 6!

Jeśli chodzi o tę drugą informację - w zasadzie otrzymywane odpowiedzi są obojętne. W przypadku pierwszej, najistotniejszą wydaje się być ta, zawarta tutaj: https://bugs.launchpad.net/ubuntu/+sour ... bug/276573 a w szczególności w jej #13. Wynikałoby z niej, że problem leży w apparmorze. Cóż, zrobiłem to, co jest tam podane i różnica jest taka, że obecnie po puszczeniu czegokolwiek do druku, drukarka "odzywa się", tj. coś tam posapie, "rozgrzeje się" i tyle.
Po nakazaniu wydruku, CUPS przechodzi w stan (wydruk) "zatrzymany".
W systemie, jak wspomniałem CUPS 1.4.2, apparmor 2.5-0ubuntu3, foomatic-filters 4.0.4-0ubuntu1
