So far, this has only been reported on Trusty. It's still unclear to us why this is occurring only on Trusty. Given that we still don't have a proper fix in place for this on Trusty, we are just going to revert the offending commit and get an SRU out with only this reversion as soon as possible.
Thanks for everyone's patience and trying to help us debug this! ** Also affects: unity/7.2 Importance: Undecided Status: New ** Changed in: unity Status: Confirmed => Invalid ** Changed in: unity (Ubuntu) Status: Confirmed => Invalid ** Changed in: unity/7.2 Status: New => In Progress ** Changed in: unity/7.2 Importance: Undecided => Critical ** Changed in: unity/7.2 Assignee: (unassigned) => Christopher Townsend (townsend) ** Changed in: unity/7.2 Milestone: None => 7.2.6 -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Then when I try to unlock the screen I need to enter my password twice (with no error message after the first try). Once logged in, all applications are closed. Uptime is still running (since no reboot) and services too (with no interruption). Looking at the apport.log file (see attached) it seems that when I try to lock the screen, compiz crashes. I've attached the compiz crash file too (_usr_bin_compiz.1000.crash) but without the 100Mo data of base64 core dumb… I'm using Ubuntu 14.04 AMD64.
