Your repository has somehow suffered some corruption.
I suggest the following procedure:
1) Change the checksum in the database (see below)
2) Use "svn log" to see all files which changed in the problem revision.
3) Use "md5sum" to find the file which matches the "actual" md5sum from the error message.
4) Examine its content, looking for corruption
How to change a checksum in the database:
*Using a _copy_ of your repository*
cd <the db directory within the repository>
db_dump -kp representations > representations.dump
The dumpfile will contain lines like:
w
((fulltext 1 7 (md5 16 \fa\85\a5\e3\bdN7\95\03\e8\baq0\ad\9cn)) w)
x
((delta 0 (md5 16 \dfV\c9\88BZ>\9fn\9bg1\a6\d4\9a*)) (1 0 ((svndiff 1 0 2 1x) 2 13 2 1c)))
Edit the part after "(md5 16 " to 16 repeats of \00 - the all-zero checksum matches anything.
db_load representations < representations.dump
Max.
