Hello Michael,

Agreed that Subversion shouldn't crash on that.

I don't have much time to look into it further, but I've quickly done
a few tests on the command line. It seems you only get this crash if
you use a backslash (which is normal on Windows of course) after the
'D:'. If you use a forward slash it doesn't crash.

So it seems that in that particular case, in libsvn_subr/dirent_uri.c
[1], svn_uri_is_canonical() does not agree with the output of
svn_uri_canonicalize().
