ValueError: '..' segment in 'portalvwco.catalog.srv.br/common/nessComponents/xtree.html?css=../../prg' cannot be walked

Not sure if that's something we just cant support (if so, why are we crashing?) or a legitimate bug

Start with warc2zim/url_rewriting.py at get_document_uri, then trace the call from warc2zim/content_rewriting/generic.py:225. Reproduce the failure using the relative URL and query string shown in the traceback. Done means the rewriter has defined behavior for this input and the conversion no longer crashes unexpectedly.
