1223	got 'WrongSegmentError' during repair	francois	somebody	"As I was working to improve the logging of 'tahoe deep-check' and 'tahoe check' (another ticket coming soon), I manually deleted shares from two different tahoe nodes to manually trigger a repair.

Encoding parameters of this file were M=66 and K=22.

The complete debug log as extracted by 'flogtool' is attached to this ticket.
