This morning upon starting my Kubuntu, I had a system message saying knetattach had closed unexpectidly. This is the first time I see this message. I read about it and I do not understand why I would have this error when I have no network sharing with anything. I only have normal Internet access.

The last thing I did on my Kubuntu was the system update a few days ago. The only internet types of software I use are Firefox and sometimes Bittorrent.

Why am I having this error ?
