Debugging strange "corrupt pack" errors on SuSE 9

A colleage at work is using git to manage code updates to a heavily
firewalled machine at a client site. In a nutshell, we "push" the
interesting code to a repo on usb-stick, and we pull from it on the
client's machine.

We do some coding and testing on that machine, so ocassionally we
bring some patches back.

Now the working repo on the client machine has started to die with
"corrupt pack" errors. I am trying to get my hands on the literal
error messages, and exact software versions installed. Right now all I
know is that it is SuSE 9 x86, git 1.4.x, cogito .17.x . The error
appears on git-diff, git-fsck-objects --full

We did bring a copy of the working copy with the "corrupt pack" to our
office, and here git (v1.5.1 and 1.5.2) thinks it's perfectly well.

So I am a bit puzzled - while we try to get 1.5.x on the client
machine and see what happens, is there anything that could be causing
this? Any additional tests that we should run?

cheers,
