The immediate fix is attached. It's rather trivial. 8=] Also of note is
that it fixes the Python test I was struggling with.

AFAIK you've already been given partial commit access.
As a partial committer you can commit any diff outside of your area
as long as a full committer gives you a +1.
So you can commit this yourself, and include this line in the log message:

Well it keeps going on like this and I can't think of more
inventive things to say.
I've scanned the rest but couldn't find anything wrong with it.
The compiler here is also happy with the patch applied.
With fixed parameter indentation, I'd say +1.
svn patch is not able to digest this diff by the way.
svn: In file 'subversion/libsvn_client/patch.c' line 2201: assertion
failed (target->current_line == hunk_start)
Aborted (core dumped)
But that's likely to be entirely my own fault and not yours, so it does
not count towards the review :)
Thanks,
Stefan

This patch seems similar to what I posted in
http://subversion.tigris.org/ds/viewMessage.do?dsForumId=462&dsMessageId=2359987
but failed to express accurately what the problem was in prose. Thanks Roman.
And it does cause the Ruby bindings to not segfault for me locally. (I get 6
errors and 1 failure). I will continue to look into this as time allows.
