[Bug 829221] Re: lightdm crashed with SIGSEGV in initialize_password_db()
Ok, since we have people available to test, I've gone ahead with
uploading a package with this patch applied to oneiric-proposed. It
should be reviewed and accepted by the SRU team in the next few days, at
which point you will be able to test the fix by installing the libpam-
smbpass package from -proposed. Please report any results here, so we
know whether to push this fix out to the rest of our users and forward
it to upstream.
