Bug Description
Since more or less a month ago I experienced OS crashes when clicking any panel button (calendar, volume, battery, etc). Only the mouse pointer still moves, but the system becomes totally unresponsive so I have to force power-off. I checked my syslog and the message before the power-off was:
Jan 16 14:13:07 jeco-pc kernel: [18048.538695] unity-panel-
I thought it was a similar issue as reported in https:/
I checked my syslog again and the message was:
Jan 17 09:38:12 jeco-pc kernel: [ 2911.154812] traps: unity-panel-
Following instructions posted in the question #663175 in launchpad, I ran an apt-get dist-upgrade. After that, the system worked well for one day. But now, the problem returned with the log:
Jan 31 15:56:19 jeco-pc kernel: [ 3005.862110] unity-panel-
Again, any click on a panel button means a system crash and a forced power-off.
