My packages have been updated. I don't know if this automatically generated report will provide you with the info it produced, because this is a duplicate. This was a bug that I reported manually for the lightdm package but for a different symptom. Bug https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/813390 This was further identified as a duplicate of https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug809890 . Please let me know if you want me to send more info or just file a new bug when this pops up again. Thanks!

lightdm updates are being blocked due to dependency issues, so this bug will continue to exist until that is resolved.
