Bus Error in 0.33.1

[Dietrich Epp <di...@zdome.net>]

I'm using Subversion 0.33.1.  I mistyped a command and Subversion gave 
a bus error.  I was in a working copy and I typed "svn st ..".  The 
parent directory was not a working copy.  I reproduced this in a few 
cases, always where I was in a working copy and tried to get the status 
of the parent directory which wasn't.

It looks like dereferencing a NULL pointer to me, but I'm not very 
familiar with the project.

The end of the backtrace looks funny, when I got this error in 0.33.0 
it ended in 'main'.

Thanks, I was able to reproduce this bug easily, and filed it as issue
1617.
