I am getting this message agter a series of updates on 05/17/2014:
If I click Report problem..., I am asked for a password to acess logs. These windows do not identify themselves and it is difficult to see what the source is in System Monitor. If this is a Linux task generated ny the OS, it seems to be a security risk.
I saw a post that I should do:
sudo apt-get update && apt-get dist-upgrade
So hopefully it helps.
