[reportlab-users] Broken code

[reportlab-users@reportlab.com]

Is anybody able to help with this one? Attempting to run code that has run =
perfectly for over a year on our previous box (probably with a previous ver=
sion of Reportlab), fails on a fresh install with the latest version (downl=
oaded in the course of a long weekend rebuilding the server...!).

Traceback (see foot for full version):

  File "/usr/local/lib/python2.3/site-packages/reportlab/pdfbase/pdfdoc.py"=
, line 1839, in format
    dict["Filter"] =3D PDFArray(map(PDFName,self._filters))
AttributeError: PDFImageXObject instance has no attribute '_filters'

Any help would be most appreciated.
