corrupted files not reported

[Brian Z]

Binary package hint: pdfshuffler

A corrupted file can be opened, and edited, but not saved. When I try to save it, the "Export..." dialog window simply stays open, with no error message or other indication as to why nothing is happening.

I only understood that this was because the file was corrupted after I filed invalid bug report #608870.

Running pdfshuffler 0.5.1 from a terminal window, I import several PDFs, and I can see from the terminal window that one of them is regarded by pdfshuffler as corrupt as it shows an error in the terminal window.

If then I delete the corrupt file from the pdfshuffler window, the remaining files cannot be exported. The same error message occurs in both cases.

 It seems that a corrupted file spoils the entire session and you need to close the program and start again.

The error I get when I try to export the attached file is:
Traceback (most recent call last):
  File "/usr/bin/pdfshuffler", line 417, in choose_export_pdf_name
    self.export_to_file(file_out)
  File "/usr/bin/pdfshuffler", line 438, in export_to_file
    pdfdoc_inp = PdfFileReader(file(pdfdoc.copyname, 'rb'))
  File "/usr/lib/pymodules/python2.6/pyPdf/pdf.py", line 277, in __init__
    self.read(stream)
  File "/usr/lib/pymodules/python2.6/pyPdf/pdf.py", line 651, in read
    offset, generation = line[:16].split(" ")
ValueError: too many values to unpack

Interestingly, the 'corrupted' file I have just tested this on was produced by Ubuntu's Simple Scan (in text mode, 150dpi), and it displays fine in Adobe Reader 9 or Document Viewer 2.32.0. I've rescanned it 3 times and it still breaks pdfshuffler.

I'm using Ubuntu 10.10, 32-bit version.

An update to 0.5.1 was provided. Please restest and reopen this bug if the problem still occurs.

For a reason, I doubt any reasonable change in pdfshuffler would help.

The problem - in a way - lies in pyPDF, or more exactly in Simple Scan producing corrupted pdf files.
