my auto gc kicked in, and shows this:

fatal: corrupt packed object for 2c1e128aa51e3a64bd61556c0cd488628b423ccf
error: failed to run repack

Fortunately, I have the uncorrupted object somewhere else.  So I copy the 
single object as a loose one, and all is fine.  Right?

Wrong.

Repack still picks up the corrupt object instead of the good one.  What's 
the best way out?

Use a 1.6.0 rc?  Nico I thought fixed this in 1.6 to automatically
try and find another copy of an object if the first copy considered
for inclusion into the pack was corrupt.

Thanks for the quick reply, but no joy (You should know me better than 
that ;-) :

$ git --version
git version 1.6.0.rc1.112.gebbe4

Just for bullocks, I gave it a try with git version 1.6.0.rc1.141.g0d7ea.
That is rc2+26 patches, in case you are interested.

Unfortunately, each test costs me

(including the inability to work properly because of all the swapping) 
which is not really nice, as the corrupt packed object occurs during the 
last 20% of the _writing_ phase of 60104 objects.

Oh, and they are big objects.  The corrupt one is 65 megabyte, for 
example.
