Package: matplotlib
Version: 0.90.1-4
Severity: important
An API changed between Python 2.4 and Python 2.5 such that matplotlib
0.90.1 can no longer output PDF files using its (non-Cairo) PDF backend.
There is a matplotlib bug report for this issue here:
http://sourceforge.net/tracker/index.php?func=detail&aid=1738494&group_id=80706&atid=560720
To replicate run the attached Python script:
> python pdf_broken.py

AttributeError: 'module' object has no attribute 'decoding_map'
The attached patch against lib/matplotlib/backends/backend_pdf.py
corrects this issue.
I am not currently a Debian user. This issue was reported by a
matplotlib user (Lorenzo Isella [EMAIL PROTECTED]) to the
[EMAIL PROTECTED] This issue should appear
whenever matplotlib-0.90.1 is run with Python-2.5, which appears to be
only on "lenny". "etch" has matplotlib-0.87 and Python-2.4, and "sid"
has matplotlib-0.91.2 (which incorporates the included patch upstream)
and Python-2.5.
Cheers,

Version: 0.91.2-1
Hi Michael,
we uploaded[1] matplotlib version 0.91.2 in unstable a couple of days
ago, and in other few days it will reach testing (aka, lenny).
That version fixes the bug you reported, so it's just a matter of days
and your lenny machines will have the new version to install.
I tested matplotlib 0.91.2-2 with python 2.5.2 and it works as
expected (test.pdf file is generated and contains the graph).
That said, I close this bug, and I thank you for having reported it!
Kindly,
Sandro
