I have had a few reoccurrences of this problem most recently only a week or two ago. (Lesson for me is to keep a note of when and what version of Linux)
I am not sure what kernel version I was on when it last happened but I am currently on Linux 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 17:34:21 UTC 2012 i686 i686 i386 GNU/Linux The problem was intermittent (and relatively painless) but I would need to be crash free for about a month before closing it. I have tried to run 'apport-collect -p linux 783458' but cannot as normal user running 'apport-collect -p linux 783458' I get... "ERROR: connecting to Launchpad failed: [Errno 1] Operation not permitted: '/home/peter/.launchpadlib' You can reset the credentials by removing the file "/home/peter/.cache/apport/launchpad.credentials" Following the reset instruction 'rm /home/peter/.cache/apport/launchpad.credentials' I get... rm: cannot remove `/home/peter/.cache/apport/launchpad.credentials': No such file or directory using 'sudo apport-collect -p linux 783458' I get a Chromium Info window saying... "Chromium cannot be run as root. Please start Chromium as a normal user. To run as root, you must specify an alternate --user-data-dir for storage of profile information."
