pypdf assert error on documentinfo

[Tim Arnold]

Using pyPdf, nice user interface. Maybe it doesn't handle pdf 1.4? I'm 
getting an assertion error from the following code. The pdf file shows it 
does have a title in its document info (using acrobat 8 or reader 5).

pdf is version 1.4, produced with pdfeTex (pdflatex) 1.304
using python 2.4.1

#==== file test.py ====
import pyPdf
filename = 'test.pdf'
test= pyPdf.PdfFileReader(open(filename,'rb'))
print test.getNumPages()
tmp = test.getDocumentInfo()

===========
python test.py
55
Traceback (most recent call last):
File "test.py", line 6, in ?
    tmp =  test.getDocumentInfo()
  File "tiarno/pyPdf-1.9/pyPdf/pdf.py", line 291, in getDocumentInfo
