Package: ghostscript
Version: 10.05.0~dfsg-1
Severity: normal

There seems to be a regression in ghostscript 10.05.0~dfsg-1:
ps2pdf generates larger PDF files than with 10.04.0~dfsg-2.
For instance:

With 10.04.0~dfsg-2: 92516
With 10.05.0~dfsg-1: 99089

Note: the input PDF file was generated by pdflatex. It does not have
any image, just text and math.

I don't have the time to investigate right now...

And I could not have any expected cause in the Ghostscript 10.05
release notes. So I'm wondering whether this is an upstream bug.

I've eventually found the cause (about fonts), and this was a bug
in Ghostscript 10.04:

So, closing.
