This was supposed to be fixed with f840149.
When does It happen: on load, even when ext-persist is not enabled?
Can you retry with a non-minified version, and share the stack trace.

I'm not using ext-persist and now I realize it is happening with the minified version only.

With the non-minified version I get these warnings only (not the Jquery one) but the result is the expected one:
jquery.fancytree-all-deps.js:1548 Fancytree assertion failed
jquery.fancytree-all-deps.js:1548 Could not access window.localStorage
jquery.fancytree-all-deps.js:1548 Fancytree@1

Note: I'm using wkhtmltopdf, a webkit based PDF rendering engine.

I don't see a reason why the minified version should behave differently.

Anyway, wkhtmltopdf uses a 2012 webkit and is not well supported anymore, also difficult to debug, so I don't want to invest much effort here. I am open to patches though.

As a workaround, you could remove the ext-persist plugin from the minified JS file.
