I apologize if my lack of understanding has led me to a wrong judgement but it doesn't seem like bug 476279 is the same issue to me... The user mentions a permanent crash only fixed by restarting plasmashell and the errors in the log are completely distinct from what i was getting.

Ah sorry, my mistake, I meant to mark it as a duplicate of Bug 478309.
