Error on push (unable to create temporary sha1 filename)

Hello everyone,

I'm new to git and recently set up my own server where I can push to via ssh. It worked fine for several pushes but suddenly I got this error message:

git push origin master

Counting objects: 37, done. Compressing objects: 100% (27/27) Writing objects: 100% (31/31) Writing objects: 100% (31/31), 5.59 KiB, done. Total 31 (delta 11), reused 10 (delta 1) error: unable to create temporary sha1 filename ./objects/0e: File exists

fatal: failed to write object
error: unpack failed: unpacker exited with error code
To git@myserver.de:django.git
 ! [remote rejected] master -> master (n/a (unpacker error))
error: failed to push some refs to 'git@myserver.de:django.git'

I didn't changed anything on the server and haven't done anything special in my local copy (just added/edited files). How can I fix this? (Already tried cloning my repository locally and push from the new one).

Thanks in advice, Jan
