I cannot find bug #1745259 or any other bug about this issue. I have light-locker crashing frequently on bionic.

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

I try to click on the other duplicate bug but the link doesn't work. Seems to be because it's a private bug. How can I get more information on this, if it is marked as a duplicate of a bug I can't access?
