Problem with git-push

Hi list,

I'm having some weird issues with git-push lately (1.4.1 on both ends):

: flz@cream:/tinderbox/portstrees/xorg-modular/ports; git push
updating 'refs/heads/xorg'
  from 6d1e4fce0a22da799175ec8e168dc0767f1131ef
  to   496cbd4c75220c204aac4fd1ef9912e40e0314b2

Any idea what that could be?

Cheers.
