Normally I run from the latest source code and the last binary install I had done was 0.8.52 (everything working fine). I just installed the binaries for 0.8.53, then I also find that calibre crashes with 0.8.53 (but only when scanning PDF files.)

Which implies that perhaps Kovid "broke something" in the PDF code (which being C++ is the most likely thing to cause such a crash).

@Kovid - here is what my code does where I believe it is crashing:

Spoiler:

    def _read_pdf_txt(self, book_path, start_page, end_page):
        from calibre.constants import plugins
        pdfreflow, pdfreflow_err = plugins['pdfreflow']
        with open(book_path, 'rb') as stream:
            tdir = PersistentTemporaryDirectory('_isbn')
            with CurrentDir(tdir):
                pages = pdfreflow.reflow(stream.read(), start_page, end_page)
                with open('index.xml', 'rb') as f:
                    xml = f.read()
                    #open('E:\\%d.xml'%start_page,'wb').write(xml)
        root = etree.fromstring(clean_ascii_chars(xml))
        txt = etree.tostring(root, method='text', encoding=unicode)
        return (pages, txt)
