fatal: unable to run 'git-svn'

Hi,

I am not sure whether this is right place to post such question. 

I've been using git svn with different svn repositories for some time now. But I have one repository with which a git svn clone always fails at the same revision. There is no problem when using svn checkout on that repository. I do the following:

$ git svn clone https://....some_pivate_server:2443/svn/Foo/trunk/bar/

...
several hundered revisions are imported
...
r896 = 6a91d0d15864c174fe8d001e03c579d1968ab926 (git-svn)
	A	Uebungen/uebung08/README
r897 = c2d0e0f317b54575598c8d3067f26a558b202745 (git-svn)
fatal: unable to run 'git-svn'
$

This is on OX 10.5.6 with
$svn --version
svn, version 1.6.1 (r37116)

$git --version git version 1.6.2.2

I tried raising limits for the number of open files and user processes. But that did not change anything, it still fails at the same revision. Any pointer where to search for the reason would be great.
