systemd-logind crash at login or on sudo su (not sure which)

[Jb]

What I expected to happen. No crashing process when I log in.

I had previously shut down the virtual machine just fine so this was from a fresh power on. I logged into the system and got the attached crash.

This is likely unrelated, but I had just logged in, opened a terminal (control-alt-t) and typed "sudo su" and had not entered my password yet, when the crash screen showed up.

I hope this can help you trouble shoot the problem as I have seen similar crash-after login problems with Lubuntu before. In all cases everything seems to run fine after the task crashed.

[Apport retracing service (apport)]

This crash has the same stack trace characteristics as bug #1495178. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.
