db11617ef1454332336e00abc311d44bc698f3b3 is the SHA-1 of the actual
pixel shader file I'm trying to commit; in other words, it doesn't
seem to be a hash of a special format.  Similarly,
c9f4fabc4d093612fece03c339401058 is its MD5.

I had our server admin run the commands:

[root@meow ~]# svnadmin verify -r604440 /srv/subversion/repositories/meow/
* Verifying repository metadata ...
* Verified revision 604440.
[root@meow ~]# svnadmin verify -r605556 /srv/subversion/repositories/meow/
* Verifying repository metadata ...
* Verified revision 605556.

("meow" replacing confidential names.  No I don't know why the server
admin is running svnadmin as root >.<)

I was able to branch (svn copy) the affected branch to a new branch,
and committing the same file to the new branch has the same error.
Checking out that revision works fine; only that commit is affected.

I started an svnsync yesterday to clone the repository to my desktop
machine.  It's at revision ~150000 now, so maybe on Monday or Tuesday
I'll be able to try things safely on my local machine.

Once it's on my local machine, I'll be able to compile TortoiseSVN and
debug it while pointing to a file:// repository.  (TortoiseSVN instead
of command-line svn because TortoiseSVN is compiled with Visual C++
and is therefore many times easier to debug.)
