Segfault during "svn info"

Hi,

there seems again a problem if the URL of a repository is like
svn+ssh://svn@10.0.1.1. I'm using trunk, r33797.

This time it's not about accessing the root of it (and the question
how to ensure that 10.0.1.1 is not a PEG revision) but about Subversion
internal handling of this.

Calling
$ svn info
in a subdirectory of my repository results in a segfault.

"svn+ssh://svn@10.0.1.1") at

1029 while (*ptr != '/')
(gdb) print ptr
$1 = 0x67b000 <Address 0x67b000 out of bounds>
