Failed to execute 'pushState' on 'History'

[drnextgis]

I've downloaded shower.zip from starting page but when I open index.html in Chromium and try to switch to second slide - presentation automatically goes to list mode and I get error in console:

Uncaught SecurityError: Failed to execute 'pushState' on 'History': A history state object with URL 'file:///home/dr/tmp./index.html?full#Cover' cannot be created in a document with origin 'null'.

The same presentation works fine in Firefox.

It’s a known issue caused by the new Chrome (since 45 or so) security limitations: it’s not allowed anymore to manipulate history for file:/// protocols. It could be easily solved by using local server: python -m SimpleHTTPServer 8000, for example. There’s also a patch removing History API usage from Shower’s core (replacing it with localStorage states), but it’s not merged yet, but it will be soon.
