500 error when opening project page

Updated to GitLab CE 8.9.6 on Ubuntu Server 14.04 LTS via apt. After verifying that the upgrade had successfully happened, I tried to navigate to one of our project pages. Instead of seeing the project page, I get a page with a 500 error. The included data snippet is from the production log, and is actually entered twice each time someone attempts to navigate to the project page. If I manually navigate to the ...project page/activity page, everything works fine.

The stack trace seems to not like something about our SSL certificate, but I'm not sure what that could be. It's a relatively new cert, 2048 bit RSA with a SHA-256 signature.

I have the same issue, on some projects but not all

Same Problem Here!

There is a workaround described here: https://gitlab.com/gitlab-org/gitlab-ce/issues/19073#note_12712670

We're working on a fix for 8.10.
