git-svn breaks svn when adding .svn

Hello dear git list!

The following information was submitted to me by Frederik and is forwarded to the list, because he's no mail access right now:

Using "git-svn dcommit", files or folders named ".svn" can be committed to the Subversion repository.
This breaks the SVN repo - e.g. "svn update" results in the following error:
    svn: Failed to add directory '.svn': object of the same name already exists

Ideally, the SVN server would reject such a commit.
However, if I interpret the following issues correctly, Subversion doesn't want to handle this server-side:
    http://subversion.tigris.org/issues/show_bug.cgi?id=1068
    (also: http://subversion.tigris.org/issues/show_bug.cgi?id=1065)

Since this is potentially a very critical issue, I suggest git-svn dcommit check and filter for such occurrences. Alternatively, a prominent warning could be added to the relevant git-svn commands.

Details:
    git version 1.5.4.3
    svn version 1.4.6 (r28521)
    Plattform: Ubuntu 8.04 Hardy Heron
