[Bug 829221] Re: lightdm crashed with SIGSEGV in initialize_password_db()

[Tamer Saadeh]

Dear Steve,

I am unable to report any further details about this bug, since I upgraded a
month ago and my computer crashed. With other complications in the way of
fixing the laptop, I wasn't able to fix it until last week. My fix is
actually a complete re-install of Natty, then upgraded to Onieric. That
said, I do not have the same configurations on my laptop, which happens to
cause many of the bug I was facing to disappear. Therefore, I think it is
safe to say that this bug is incomplete or fixed.

Sorry for the delayed response,
Tamer
