strange error while pushing

I was going to push some stuff I'm working on to my repo at repo.or.cz, and just got the following error:

$ GIT_TRACE=1 git push kusma work/daemon-win32:work/daemon-win32-process

Is this something anyone have experienced before?

I'm not entirely sure if this happens on the local side or the remote side... I've tried with a few different versions locally but the issue seems to persist, so I'm starting to suspect it's an issue at the remote end. Any insight, anyone?
