fatal read error in cloning/pulling git repository

I'm using Git for Windows (git version 1.7.4.msysgit.0) on my system, and it's worked perfectly most of the time, but today at uni I'm having problems whenever I try to git clone or git pull or get fetch a repository (for reference it's git://git.ffmpeg.org/rtmpdump ) and I get:

fatal: read error: Invalid argument

Using GIT_TRACE=1 shows the problem with git fetch, but it fail开发者_开发百科s no matter the arguments. Could it be to do with my network or my local copy of git?

Check if you have other version of mingw32.dll in your computer. You need the correct mingw32.dll on the PATH before other versions.

If git fetch doesn't work at all for you with https:// or git://, it really sounds like a corrupt installation, or a bug. If you'd like, head over to the msysGit mailing list to log your bug report.
