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.

@ andrew, please:

1. Edit the description, so it explains which consequences has this bug.
2. Set the status back to "confirmed".

Thank you.
