I just experienced this bug for the 2nd time in 8 days. The system had been on for an hour or so and I was playing chess using an app that runs under WINE that I use regularly without the 100% CPU problem occurring. Thunderbird and Firefox were open but I was not interacting with them. The System Updater notified me of an available update and I went ahead and let it update while I was playing chess. Shortly afterward, the cooling fan came on and I checked the System Monitor and found one CPU pegged at 100% (see screen shot 1). The process consuming 25% of the CPU was hud-service. (One of four cores running at 100% = 25%). I glanced at some logs bug didn't know what to look for. Rebooted Ubuntu and CPU activity is back to normal. I'm going to scan my system log for clues but don't know what to look for; if I find something suspicious I'll post it here. You can ask me to look for specific things in the log and I'll be glad to do that. 2 screenshots attached.
