This approach "sort of" worked, i.e. it worked insofar that I was able
to use the repository enough to generate a series of patch files for the
developer's work from the last two weeks to be applied to their new
clone of the central repository. Why I did this is answered below ;)

See if "fsck --full" complains after that.  If the repository was not
repacked during that period, all objects created by the activity by the
unfortunate developer would be loose, so ...

tyler@ccnet:~/source/slide/brian_main> time git fsck --full
Segmentation fault

Oh well, your approach worked *enough* to get the important data out,
and that's what's most important.


Moving forward we're likely going to implement an automated process of
walking through developers' repositories and pushing any unpushed refs
to a backup repository just to make sure something like this doesn't
happen again.


Appreciate the help :)
