Well, I didn't mean to piss anybody off or anything like that, In fact, when
I replied to you I didn't set the severity back to critical and instead I
just commented why I though it was like that.

I just wanted to report a bug wich causes unrelated software on the system
(acpi scripts) to fail and introduces a security problem (xscreensaver is
not being told to lock the session on hibernation or laptop lid signals),
any of these two things are enough for a critical severity accordingng to
bug-maint-info.txt:

   critical
          makes unrelated software on the system (or the whole system)
          break, or causes serious data loss, or introduces a security
          hole on systems where you install the package.

Sorry, I couldn't find any info on this on the policy, if you are so kind to
tell me why this should not be critical, I'd love to know it.

I'd provide a patch if I knew how to solve the problem, but I don't, if you
could tell me how to provide more info I'd be happy to report it.

Different? I don't get what info you are asking me for.

Like I told you it is failing for me on the two machines on which I have
installed it, one is running wheezy and the other is running sid, both are
amd64, but for what I can read it is also failing for other people on other
arches, at least i386.

Confirm that the bug is the same one? seems so, yes.

For what I see they have tried changing some pam stuff without any success,
and I haven't modified that at all.

It is difficult for me to know why it fails as I'm not able to get it to
work, I'm adding at the end of the mail a debug of a session of lightdm on
which I logged in as manty and then logged out, then killed lightdm, so that
you can compare this with your working session.

Let's hope we can find something here as I don't know what else to add to
the bugreport.

Regards.
