Wiki pages are not visible after upgrade to 8.0.3

Summary: after upgrade to 8.0.3 wiki pages are not visible in all projects. This includes "Pages" and "Home" tabs. Wiki repositories are all there, but it seems gitlab can't find them. If i clone wiki repository, I can see all the pages there.

When attempting to add new page to wiki, I get 500 error, production.log:

Completed 500 Internal Server Error in 102ms (ActiveRecord: 10.5ms)

NoMethodError (undefined method `escaped_url_path' for nil:NilClass):
  app/models/wiki_page.rb:172:in `set_attributes'
  app/models/wiki_page.rb:192:in `save'
  app/models/wiki_page.rb:139:in `create'
  app/controllers/projects/wikis_controller.rb:60:in `create'

After attempting to save the same page again, i get an error:

Duplicate page: Cannot write //home.md, found //home.md.

Any update on this ? The same happens even with 8-2-stable

We have tons of wiki pages in our gitlab and all of these are unavailable

mentioned in issue #3993 (closed)

Is this still an issue?

Added wiki label

Yes, i'm still unable to see wiki pages

Even on latest 8.3? Can you try to update to 8.4 when it comes out tomorrow and see if it's still an issue? Also if the logs differ from the one you posted in the issue, please share them as well.

I've upgraded to 8.5 and this issue is still present. Wiki pages are not visible.

I cannot reproduce this on the latest release GitLab 8.10. Please try to update and report back if the error still exists.
