Its the size of the fetch. The day before you probably had a smaller number of objects downloaded (<100) so Git used unpack-objects instead of index-pack. Yesterday it was a larger download (>100), so it used index-pack.

In 1.6.0.2 index-pack writes a temporary file to .git/objects but later tries to rename it into .git/objects/pack. That renaming must not be working on sshfs.

Latest "master" has a change from Pasky (8b4eb6b6 "Do not perform cross-directory renames") that should fix this issue. Or just don't use sshfs. Or teach sshfs to rename across directories.
