Bug#398893: open_basedir doesn't allow to go 'back' to my basedir

[Evgeni Golov]

Package: libapache2-mod-php5
Version: 5.1.6-5

I have an apache2 with php5 running (packages from Etch).
I use open_basedir /path/to/scripts/ in my configfile. When I try to do
an is_dir('/path/to/scripts/blah/..') I get an:

open_basedir restriction in effect. File (/path/to/scripts/blah/..) is
not within the allowed path (s): (/path/to/scripts/)

But '/path/to/scripts/blah/..' is '/path/to/scripts/' and it IS the
basedir.
When I change open_basedir to /path/to/scripts (without the / at the
end), the is_dir() works like it should.

Is this a correct behavior and I'm missing some important infrmation
about the work of open_basedir or is this a bug?

kind regards
Evgeni Golov
