unable to get type of object

I'm having one of those nasty 128 errors which I cannot debug:

************
predircam@eduab:~/public_html/idosing> git pull
Generating pack...
Done counting 117 objects.
error: unable to find c3117d23df0c01ba8558bad81ad3488f0e8d430a
fatal: unable to get type of object c3117d23df0c01ba8558bad81ad3488f0e8d430a
fatal: early EOF
fatal: git-unpack-objects died with error code 128
Fetch failure: /home/predircam/gitrepos/idosing.git
***************

google suggests me to run git fsck to get a list of corrupted files. 
Besides that I'm running git 1.2.4 and that the git command for that 
version is fsck-objects, I'm not having any result at all.

Could this be a compatibility problem? As I said, I run git 1.2.4 on the 
repo server and git 1.7.0.2 on my development server. BTW, on my devel 
server running the git command fsck gives no result either.

I would appreciate any help.

Thanks
