Problems accessing GitHub's SVN-bridge with SVN 1.11

Hi all,

GitHub documents to support Subversion clients and I'm using that for
many projects to include them in one of my working copies using
svn:externals. Since upgrading TortoiseSVN from 1.10 to 1.11 I get the
following error for all of those projects:

> The server at '[...]' does not support the HTTP/DAV protocol.

This happens to a long list of projects, some examples:

> https://github.com/apache/commons-lang.git/tags/LANG_3_6
> https://github.com/pgjdbc/pgjdbc.git/tags/REL42.2.2
> https://github.com/ams-tschoening/kaitai_struct_tests.git/branches/libs_java_3rd_usage

I've asked about that problem on SO[1], which revealed that the switch
from 1.10 to 1.11 really is the problem. Downgrading resolves the
problem.

Do you have any idea what could be the root cause? Is there something
that needs to be configured specially?

Thanks!
