 From what I can tell, Francois's exception can only occur when trying  
to repair a file that is currently unrecoverable (fewer that 'k'  
shares visible). The 'download_version()' call in his stacktrace is  
only used by the repair code path. I looked and did not find any  
smoking guns in the --add-lease path.. I suspect that the server  
connections simply got established in between Francois' first and  
second commands.

I'm poking at the repairer code to report a better description here.  
There wasn't a check to make sure that at least one version was  
recoverable before it tried the download-and-upload repair cycle.

I wouldn't be surprised if #768 is another expression of the same  
thing, though.

cheers,
