Comment 13 for bug 779908

Hello

I get this problem:
I tried to work with pdftk and pdf chain. But I get often this error message:

baumtopf@ubuntu:~$ pdftk eee.pdf fff.pdf ggg.pdf cat output merged2.pdf
Unhandled Java Exception:
Unhandled Java Exception:
java.lang.NullPointerException
   at gnu.gcj.runtime.NameFinder.lookup(NameFinder.java:201)
   at java.lang.VMThrowable.getStackTrace(natVMThrowable.cc:44)
   at java.lang.Throwable.getStackTrace(Throwable.java:524)
   at java.lang.Throwable.stackTraceString(Throwable.java:419)
   at java.lang.Throwable.printStackTrace(Throwable.java:365)
   at java.lang.Throwable.printStackTrace(Throwable.java:354)

and I cannot take a look at the merged pdf file and this error message comes:

"PDF document is damaged"

Later I tried this:
baumtopf@ubuntu:~$ LANG=C pdftk eee.pdf fff.pdf ggg.pdf cat output merged2.pdf
Unhandled Java Exception:
Unhandled Java Exception:
java.lang.NullPointerException
   at gnu.gcj.runtime.NameFinder.lookup(NameFinder.java:201)

   at java.lang.Throwable.printStackTrace(Throwable.java:365)
   at java.lang.Throwable.printStackTrace(Throwable.java:354)

I refer to this link:

https://bugs.launchpad.net/ubuntu/+source/gcj-4.4/+bug/487922

But this error message comes always.
And the links where I can download PDFTK from jauntry don't work:

http://de.archive.ubuntu.com/ubuntu/pool/universe/p/pdftk/pdftk_1.41-3ubuntu1_i386.deb
http://de.archive.ubuntu.com/ubuntu/pool/universe/p/pdftk/pdftk_1.41-3ubuntu1_amd64.deb

Also I looked for these packages pdftk_1.41-3ubuntu1_i386.deb and pdftk_1.41-3ubuntu1_amd64.deb in Google. But I cannot find Downloads of these packages.

Please help, what can I do?
