Knotify

[fredflinstone]

Ciao !
Da qualche tempo mi appare in continuazione il seguente messaggio :

Executable: knotify4 PID: 7593 Signal: Segmentation fault (11)

Che fare ?
Grazie.

Ciao,
se l’errore ti compare nella finestra del crash manager di KDE dovresti poter accedere ad un tab che contiene il backtrace, che sarebbe utile visionare.
Per avere un backtrace con informazioni utili sarebbe prima opportuno installare almeno i seguenti pacchetti:
kde-runtime-debug kdelibs-debug

Ciao !

Ecco il backtrace :

Grazie.

[Silvan]

Ciao,
il bug upstream è questo: https://bugs.kde.org/show_bug.cgi?id=335111.
Come suggerito proverei da una finestra di terminale (konsole) ad eseguire questo comando:
/usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins

[Silvan]

Il comando va eseguito come superutente (con ‘sudo’ davanti):

sudo /usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins
