--- Begin Message ---Package: python-poppler Version: 0.12.1-8+b1 Severity: important Tags: upstream patch Dear Maintainer, The following code: $ cat bug.py import poppler import tempfile import urllib2 # Download a PDF. dummy, filename = tempfile.mkstemp(".pdf") pdf = urllib2.urlopen("http://www.aquilenet.fr/docs/adhesion.pdf";) local_pdf = open(filename, 'w') local_pdf.write(pdf.read()) local_pdf.close() pdf.close() # Get the thumbnail. page = poppler.document_new_from_file('file://' + filename, None).get_page(0) page.get_thumbnail() leads to a segmentation fault when the PDF file does not have a thumbnail for the page: $ python bug.py Segmentation fault Basically, the _wrap_poppler_page_get_thumbnail() function calls the poppler_page_get_thumbnail() function, but does not check that the return value is not NULL before passing it to PycairoSurface_FromSurface(), which dereferences it. The attached patch fixes this issue. The get_thumbnail() method now returns None when no thumbnail is available. I'm not familiar with the python-poppler, so this may not be the best solution (maybe an exception should be thrown instead). This error can be found in other methods, such as get_image(), so this is probably worth notifying upstream.
