Thanks for the report and research!

Maybe git-for-windows isn't filtering CRLF into LF as "git commit"
does on GNU/Linux when the original commit was made?

I had to use "git commit-tree" to reproduce the error in testing
(instead of "git commit)"

Anyways, the one-line fix below should be enough for you.
Care to give it a shot?  Thanks again.

Subject: [PATCH] git-svn: convert CRLF to LF in commit message to SVN

Subversion since 1.6 does not accept CR characters in the commit
message, so filter it out on our end before 'git svn dcommit' sets
the svn:log property.
