Permission denied ONLY after pulling bundles

Dear git group,

I would like to ask your help for a problem that we cannot fix in any way.

We have a git repository in folder on Windows.

Then we use VMware player on CentOS_6 on which we create a clone of the git repository, after of course having mounted the directory in which the repository is.

So the repository is on windows and the clone on Linux.

We are able to perfom all the git operations we need, except for the pull .bundle, which is successful in itself but prevent us from pushing after that.

As we try to push after pulling a .bundle in a branch we get the error message

NODE1:fdp> git push Counting objects: 1977, done. Delta compression using up to 2 threads. Compressing objects: 100% (423/423), done. fatal: write error: Permission denied00 KiB | 158 KiB/s error: pack-objects died of signal 13 error: pack-objects died with strange error

We have checked all the permissions, changed the users, recreated the clone but nothing worked. The push operation works perfectly until we pull a bundle. After pulling a bundle we are not able to push anymore.We tryed to delete the branches, recreate others and all works perfectly, also the push.As we pull the .bundle we cannot get the permission to do the push anymore.

What has this to do with the bundle?

Thanks for your support.
