Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Status changed to 'Confirmed' because the bug affects multiple users.

[Dave Morley (davmor2)]

The issue I see seems to come from first searching for a section in control panel. For example search for screen make a mod to the resolution and then try and open system settings.

I can't reproduce using Dave's steps on todays image.

In testing today, following an update and upgrade, experienced this with just trying to open "Sound Settings." Following reboot, no issue.
