Comment 2 for bug 242755

had to do a new install today, and used a different workaround. I think it's a slight improvement:
around line 532:

if not data.get(key):
    data[key] = value

was:
if data.has_key(key):
    raise utils.PdfReadError, "multiple definitions in dictionary"
data[key] = value

just fyi,
