I've hit this problem too, and tracked it down to what I think is a
bug in svn. It fails in libsvn_ra_serf/commit.c:close_file() on invalid
->copy_path on the file context.
AFAICT this is do to the ra_serf version of add_file() lacking
apr_pstrdup() on the "copy_path" argument passed to it; as a result it
gets overwritten with garbage on further use:
libsvn_ra_serf/commit.c:
...
1852 static svn_error_t *
1853 add_file(const char *path,
1854 void *parent_baton,
1855 const char *copy_path,
1856 svn_revnum_t copy_revision,
1857 apr_pool_t *file_pool,
1858 void **file_baton)
1859 {
...
1875 new_file->copy_path = copy_path;
..
You can apply this workaround to get it to work:

What it does is store the value to be passed to add_file() in a local
variable, and rely on perl to keep it alive through the end of function
scope, beyond the call to close_file() where it's actually used.
I'm going to submit a patch adding apr_pstrdup() to subversion folks.
Meanwhile if people find the above workarond a sensible thing to do in
git, I can submit a properly formed patch here too.
