Any hints what to do?
Regardless of any possible fault in git-svn, there's an obvious bug here
with git-fsck. Can you share the pack (if the project is public) or
compile a git-fsck without optimization and with debugging, and run it
under valgrind, to hopefully get us a backtrace of where the memory
management goes off the rails?

Unfortunately I'm unable to share the pack.
As Java Developer I'm note very savy, but I'd try.
Do you have me any pointers on ".. without optimization and with
debugging" and "run it under valgrind"?
Currently I used
deb http://ppa.launchpad.net/git-core/ppa/ubuntu quantal main
as source.

The version from the ppa seems to be 1.7.0.4-1ubuntu0.2 but the version
of git being in the native ubuntu quantal repository
(I assume you're running Ubuntu?) is already 1.7.10.4-1ubuntu1
(http://packages.ubuntu.com/quantal/git)
However to get an unoptimized version with debug symbols you could do this:
# get the source:
git clone git://git.kernel.org/pub/scm/git/git.git/
cd git
# read INSTALL, the section starting at
# > Git is reasonably self-sufficient, but does depend on a few external
# > programs and libraries
# this is a guess, maybe you need more or less packages, but you'd need the -dev packages for the C-headers
sudo apt-get install libz-dev libopenssl-dev libcurl-dev libexpat-dev
# Now disable optimizing by overwriting default compile flags:
echo "CFLAGS=-g" > config.mak
# compile and install
make
make install # installs to ~/bin
# open a new shell or relogin, and see if you're using the version you just build:
git --version
# git version 1.8.4.rc1....
