SVN Propget error linking to techno-weenie.net

After installing the plugin like this:

./script/plugin install -x http://svn.techno-weenie.net/projects/plugins/exception_logger/

I get this error when accessing the source repositories:

svn: PROPFIND request failed on '/projects/plugins/exception_logger/
init.rb'
svn: PROPFIND of '/projects/plugins/exception_logger/init.rb': Could
not resolve hostname `svn.techno%2Dweenie.net': No address associated
with nodename (http://svn.techno%2Dweenie.net)

Note the %2D (unicode equivalent of a '-').

However, when I do "svn propedit svn:externals vendor/plugins", and
copy the URL from the list (It looks right, here, btw) into a web
browser, it works. Is there an SVN Unicode setting which needs
adjusting? I posted this here, because I figured a fellow Rails
developer might have seen this.

Thanks,
Doug

Sorry. It appears this is a TextMate problem, not Subversion.
