After upgrading from texlive-2008 to 2009 on both my x86 and amd64 Gentoo systems, I discovered that all my forms/letters containing pstricks logos/graphics were missing the logo images, when compiled via "pdflatex --shell-escape letter.tex" using auto-pst-pdf: 
\usepackage[pspdf={-dAutoRotatePages=/None}]{auto-pst-pdf}

Apparently pdfcrop was not able to crop the images.
Since my logos were already cropped when I created them in Inkscape,  I worked around the issue by disabling cropping:

\usepackage[pspdf={-dAutoRotatePages=/None}, crop=off]{auto-pst-pdf}
or by using the pdfcrop option --ini:
\usepackage[pspdf={-dAutoRotatePages=/None}, pdfcrop={--debug --verbose --ini}]{auto-pst-pdf}

After looking through test.log I decided to run the runsystem() commands manually.
 
So I tried running the command
pdfcrop --verbose --debug  "test-autopp.pdf" "test-pics.pdf"

which fails:

Next, I decided to manually run pdftex on tmp-pdfcrop-5737.tex
pdftex -shell-escape -file-line-error tmp-pdfcrop-5737.tex
which segfaults.

If I run pdftex on the tmp-pdfcrop-????.tex with strace, I get
the attached strace.log
In case the segfault has something to do with my font caches
/var/cache/fontconfig
~/.fontconfig
I cleaned out my font caches:
"rm ~/.fontconfig/*" and 
"mv /var/cache/fontconfig/* /var/cache/fontconfig.bak/"
but still get same segfault.

Message:
thanks for looking at this. I tried tmp-pdfcrop-6132.tex but also could not reproduce the problem.

I took a close look at strace.log, and it seems the segfault happened while pdftex was searching for some system font stuff. Which is weird, since it should not do that.

Then I looked at the version string and it says it uses poppler. So apparently poppler has been fixed in the meantime on your system.

This is not the first time we were bitten by poppler, sadly.

Message:
Since I last reported this segfault on 2/24/10, both my x86 and amd64 Gentoo systems have apparently fixed themselves. I, too, can no longer reproduce the segfault.

Unfortunately many packages have been updated since then:
genlop -l|grep 2010 |grep "[Feb|Mar|Apr]"|wc -l
2257

including 43 dev-tex packages:
genlop -l|grep 2010 |grep "[Feb|Mar|Apr]"|grep dev-tex|wc -l
43

So I don't know what got fixed. I had been running pdflatex with pdfcrop=/None so I hadn't realized that sometime between the end of Feb and today, the pdfcrop segfault problem fixed itself. 

I no longer have "tmp-pdfcrop-5737.tex", but do have the similar "tmp-pdfcrop-6132.tex" included in the attached Bug-pdfcrop.bz2 which was created Feb 24/25.

Thanks.

can you please submit tmp-pdfcrop-5737.tex? I ran the test but didn't get a segfault. Thanks.
