Git push error: Unpack failed

[Colin Campbell]

Attempting to push a single patch, using the directions in CG 3.4.11, I 
get the console output appended. I haven't attempted anything since, and 
would be grateful for guidance from the gurus. Online research suggests 
either permission errors on the savannah repo, space issues at savannah, 
or corruption either locally or on the remote. Both my local repo and 
savannah seem perfectly normal when I look around with gitk, so I'm 
turning to the assembled wisdom for the next steps I need to take.

Cheers,
Colin
