Login Screen Problem

After updating to Yosemite, every time I start or restart my computer, the login screen shows a question mark for a login icon and says "Update required". After typing in my password a status bar shows up and completes itself, then the computer logs in as normal. Anyone have any ideas what's up with this or how to fix it? TIA.

Glad to see I'm not the only one having this problem. Hopefully someone has a relatively quick solution..

**issue fixed**

The issue seems to have resolved itself after going to "Users & Groups" in settings and resetting my user picture and saving. After the next restart, the question mark and "update needed" was gone.
