Comment 8 for bug 1718658

I faced the same issue after upgrading from Ubuntu 17.04 to 17.10 a day ago.
I'm having my home directory encrypted and I'm getting the same error message after every first login.
My home directory is mounted correctly though.

As an even worst consequense I'm not able to login into grafical environment at all: Gnome keeps crashing when I click on my user name (I even do not have a chance to enter password). Not sure, however, if this is related to the encryption issue; I'm still checking.
