[Python-Dev] Problems with revision 4077 of new SVN repository

I'm trying to mirror the brand-new Python SVN repository with SVK, to
better be able to track both the trunk and the various branches. Since
I'm not a Python developer and don't have svn+ssh access, I'm doing so
over http. The process fails when trying to fetch revision 4077, with
the following error message:

"RA layer request failed: REPORT request failed on
'projects/!svn/bc/41373/python': The REPORT request returned invalid XML
in the response: XML parse error at line 7: not well-formed (invalid
token) (/projects/!svn/bc/41373/python)"

The thread at http://svn.haxx.se/dev/archive-2004-07/0793.shtml suggests
that the problem may lie in the commit message for revision 4077: if it
has a character in the 0x01-0x1f range (which are invalid XML), then
Subversion methods like http: will fail to retrieve it, while methods
like file: will succeed. I haven't tried svn+ssh: since I don't have an
SSH key on the server.

Trying "svn log -r 4077 http://svn.python.org/projects/python/" also fails:

subversion/libsvn_ra_dav/util.c:780: (apr_err=175002)
svn: REPORT request failed on '/projects/!svn/bc/4077/python'
subversion/libsvn_ra_dav/util.c:760: (apr_err=175002)
svn: The REPORT request returned invalid XML in the response: XML parse
error at line 7: not well-formed (invalid token)
(/projects/!svn/bc/4077/python)

When I visit http://svn.python.org/view/python/?rev=4077, I can see the
offending log message. Sure enough, there's a 0x1b character in it,
between the space after "Added" and the "h" immediately before the word
"Moved".

This problem can be fixed by someone with root permissions on the SVN
server logging in and running the following:

echo "New commit message goes here" > new-message.txt
svnadmin setlog --bypass-hooks -r 4077 /path/to/repos new-message.txt

If there are other, similar problems later in the SVN repository, I was
unable to find them because the SVK mirror process consistently halts at
revision 4077. If revision 4077 is fixed and I turn up other log
problems, I'll report them as well.
