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

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.

thanks. living where i do i'm a bit paranoid. also internet provision to
apartment complex was out of commission for 4 days so i'm getting all
sorts of crash notifications. i'm an old noob at this so will have to be
more careful in future to determine what requires action. all the best

This bug affects me, even with the latest updates.
Can't we get some help from upstream? Or report the bug there?
