RuntimeError: do not know how to check outdatedness of <Nanoc::LayoutView identifier=/partials/_navbar.erb>

Summary

Running the latest version of nanoc, I get this odd error. After compiling the site exactly 4 times, the compilation process goes fine without errors.

Steps to reproduce

I'm not certain how to reproduce this, or what causes this. The site that has this issue is at the following location: https://github.com/ZeusWPI/zeus.ugent.be

Expected behavior

There should be no error. After the fourth compilation, everything is fine and this error does not show up anymore.

Actual behavior

There are errors during compilation, but doesn't affect the end result

I unfortunately can’t reproduce the problem locally. Can you tell me how you can make zeus.ugent.be cause this crash, starting with a fresh clone?

[denisdefreyne]

I have a potential fix in the gh-927-layout-view-dep-tracker branch. Can you check whether this works for you?

[werthen]

A fresh clone of zeus.ugent.be didn't resolve the issue, but the fix in gh-927-layout-view-dep-tracker works like a charm!

[denisdefreyne]

Fixed in #931.
