i'd look for a 16->64 bit sign extension which should have been 16->32 
bit... or shouldn't have happenned at all.  i don't know enough about 
python typesize / sign extensions to figure it out myself.  but the ubuntu 
system probably has 32-bit uids, and you might be using 64-bit ints in 
rdiff-backup.

16-bit uids are more traditional, but 32-bits is common in new distros.
