+ I have just noticed a problem caused by the change on 3 Oct 2011, which
+ prevents pdfopt from linearizing pdflatex-generated files at least under Ubuntu
12.04:
+ [IMPACT]
+
+ pdfopt does not work on any file generated by pdflatex.
+
+ [TESTCASE]
+
+ Cited from the original reporter of this bug:
+
+ ----------
How to reproduce the problem:
- ghostscript/9.05 is used by Ubuntu 12.04. Linearizing a pdflatex-generated file
+ ghostscript/9.05 is used by Ubuntu 12.04. Linearizing a pdflatex-generated file
does not work here. For test, simply /usr/share/doc/texlive-
doc/latex/curve/curve.pdf can be used with pdfopt:
- dreibh@lupo:/tmp$ pdfopt /usr/share/doc/texlive-doc/latex/curve/curve.pdf
+ dreibh@lupo:/tmp$ pdfopt /usr/share/doc/texlive-doc/latex/curve/curve.pdf

I have therefore reverted the change in pdf_base.ps:
- 1 index 0 lt {
- - ( **** Considering object with a negative number as null.\n)
+ - ( **** Considering object with a negative number as null.\n)
pdfformaterror
+ 1 index dup 0 lt exch NumObjects ge or {

- + 2 index 20 string cvs concatstrings
+ + ( **** Considering object with an invalid number )
+ + 2 index 20 string cvs concatstrings
+ ( as null.\n) concatstrings pdfformaterror

Now, pdfopt works as before:
dreibh@lupo:/tmp$ pdfopt /usr/share/doc/texlive-pictures-
doc/latex/curve/curve.pdf y.pdf
- dreibh@lupo:~/tmp$ pdfinfo y.pdf

+ ----------
+
+ After installing the proposed package this problem should disappear,
+ getting
+
+ ...
+ Optimized: yes
+ ...
+
+ without needing to edit pdf_base.ps.
+
+ [Regression Potential]
+
+ Very low, as only a simple consistency check got removed by the patch,
+ on the rendering nothing is changed.
