Division by zero without using table_regions

Hello, I'm trying to extract tables with defaults parameters in stream mode. I try:

tables_cam=camelot.read_pdf(filepath='pdfs_files/fulltext.pdf', pages="10",flavor='stream' )

It returns;

ZeroDivisionError                         Traceback (most recent call last)

ZeroDivisionError: float division by zero

I would expect it to return no tables found (like normally it does) rather than crashing for a 0 division. How do I prevent this? PDF_FILE: fulltext.pdf

PS: If I transform a pdf page into an image, find the table area on the image and then decide to pass the corresponding area to camelot to extract the tables, is the conversion from the position on the image to the position in the pdf just pos_image * size_pdf/size_img ?
