Re: svn clone Checksum mismatch question

I hope I didn't hijack the thread with an unrelated issue.

Looking into this, the mentioned blob
264b0c5f7b3a00d401d1a5dcce67a3734f0eede3 with md5sum
f006323ff4714ca52c0228ce6390d415 is not at path
branches/foom/--omg-optimized/twisted/internet/cdefer/cdefer.pyx. The
contents of the blob is the seemingly totally unrelated LICENSE file
that is found at trunk/LICENSE and
branches/foom/--omg-optimized/LICENSE. cdefer.pyx does have the md5sum
c7ccddd195f132926e20bab573da7ef3.  Note that the branch root directory
is branches/foom/--omg-optimized (like with the branch name being
foom/--omg-optimized), not just branches/foom. Is think git-svn relies
on the standard layout being branches directly under the branches/
directory, but I don't see how this would get the paths mixed up like
this.

Looking at what was done around this commit one finds odd stuff, like
deleting directories in trunk and then copying from a previous
revision of trunk to under the branch:
http://twistedmatrix.com/trac/changeset/13611

I created a local test svn repository and tried to do something
similar but git-svn had no problem with my test.

This is issue is not critical for me in any way but if somebody wants
to look into it I am happy to help out.
