+ 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 {
- +    (   **** Considering object with an invalid number ) 
- +    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 
+ 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.
