Comment 45 for bug 774071

I am having this same problem also. I have to restart to make it go away. This happens every once in awhile. I did not notice any other processes using much cpu. It affects 1 of 2 cores. I am using LinuxMint 14.1 and will post it to that launchpad, but wanted to inform this group as LM is an Ubuntu distribution. I do not have any calendar syncing on this machine or any thing really running on it as I use it as a backup server. The only software updates that I have done relating to time was to install ntp and use over ntpdate.
