Bug#1031983: light-locker: Fails to login a user back to her previous session (session lost, new one started)

[Dimitri <tri2000@gmx.net>]

Hi,

you are right, there is a crash of the xsession, but it happens _everytime_, so it is quite annoying. I did a diff of
the Xorg.0.log and the Xorg.0.log.old files and the difference is as follows:

Now, I guess the problem is not light-locker, but the function it calls... Maybe you can give me an advice of which
package has an issue, and where to get more help ?

Thanks a lot for your time,

Dimitri

Hi, it looks like your session just crashed. Does this happen everytime or did
it happen only once? Did you get information from the logs?
