This was reported by <<user RonnyPfannschmidt>> on IRC. The following command line will fail:
$ hg clone svn+http://codespeak.net/svn/pypy/branch/dist-2.4.1 --startrev 14033 -r 14034
destination directory: dist-2.4.1 [r14033] arigo: Create the branch for experimenting with a 2.4-emulating version [r14034] arigo: Copied the Lib of Python 2.4.1 into the PyPy branch. abort: ("'http://codespeak.net/svn/pypy/branch/dist-2.4.1' path not found", 160013) }}}
It's not clear to me why this fails. The failure occurs regardless of whether Subvertpy or SWIG bindings are used.
