grphosc1x I've compared my report and it is very similar to the first one listed in the link.
The "Keyguard is not shown in 20 seconds" crash dump in the GitHub issue does not appear to me to contain any sensitive content. If you have a GitHub account and wish to post your crash dump there, plus the other details you've provided in this thread (recurrence; stock launcher; PIN in both profiles; etc), I think that would be reasonable. If you don't have a GitHub account I can make the post for you.
One other thing that might be helpful would be a list of the apps in the secondary profile.
