Marc, before you try hunting through bdb files for the checksum, try:
db_dump -kp db/representations > reps.dump
your-favourite-editor reps.dump
The file should contain lots of lines like this:
.....
36
((fulltext 1 5 (md5 16 `\f4~\d3\fc\b5\0b\b9Q\aa\c2\af\9e\86Zc)) 2 3g)
37
((delta 0 (md5 16 \e0\a8\b1"\ac\e2\ab\1d\a1\a2\c6}\deE\19\a0)) (1 0 ((svndiff 1 0 n7) 2 20 d3)))
.....
Search for the pair of lines:
4pi
((.....some data.....)
(Where 4pi is the representation from your error message)
Now, edit the md5sum to \00 repeated 16 times, and save the file
mv db/representations db/representations.old
db_load db/representations < reps.dump
You should now be able to dump the repository, but be aware that part of the problem revision will be corrupt.
Max.
