[Zope] shell command in zope on linux

[Bernd Dorn]

hi list

i try to execute a shell command (namely pdftk) from python/zope to fill 
out fdf forms in  a pdf document

this is my command, which is generated:
pdftk /tmp/tmpRy0O_T.pdf fill_form /tmp/tmpz4mEG1.fdf output 
/tmp/tmpx1TxTD.pdf flatten

the pdf and fdf files are temporary files

i have a testcase which runs the surrounding method successfully (python 
only no zope), but wenn i access the method from zope it hangs when the 
pdftk command tries to write to the output files and i have to kill -9 
the pdftk processes

i've already tried with popen3, os.system etc.

this problem does NOT occur on macos x, only on linux, for windows i 
don't know.

my linux:
Linux bd-pc 2.6.10-gentoo-r5 #2 Tue Jan 18 18:20:46 CET 2005 i686 
Intel(R) Pentium(R) 4 CPU 2.00GHz GenuineIntel GNU/Linux

is it possible that this is a gcj problem, because pdftk is java 
compiled with gcc?

output of gcc -v
