Docky padá - dBus error

[zatnaktel]

Zdravím,
už delší dobu zaznamenávám  problém s docky. Minimálně jednou denně spadne. Podotýkám, že mi to dřív nedělalo. Běžím na Linux Mint 17 MATE.
 Když jsem ho měl otevřený v terminálu, výstup v okamžiku pádu vypadal takhle:

Kód: [Vybrat]

Podle chyby jsem dohledal jakési řešení https://bugs.launchpad.net/docky/+bug/1309706/comments/2, ale nepodařilo se mi dohledat zmíněný soubor Docky.Services/Docky.Services/SystemService.cs.
Proto mám dotaz, zda-li by skutečně komentář v adrese mohl pomoci a kde se tedy soubor SystemService.cs nachází, případně čím to může být způsobeno.
Nejsem si jist, jestli pády začaly až po aktualizaci, ovšem reinstalace se smazáním dat nepomohla.

Díky moc za nápady a rady,
Zatnaktel.
