Hi,

    I just want to inform you that I probably encoutered bug in CVS
version of Horde in file Token.php. It seems to be problem caused by
usage of IPv6 protocol which is not expected by Horde.

    I have got Apache/2.0.52 (Gentoo/Linux) and I am using IPv6 to
access Horde. It is causing print of these messages into several parts
of Horde:

*Notice*: Undefined offset: 1 in */usr/lib/php/Horde/Token.php* on line *35*
*Notice*: Undefined offset: 2 in */usr/lib/php/Horde/Token.php* on line *35*
*Notice*: Undefined offset: 3 in */usr/lib/php/Horde/Token.php* on line *35

*I wrote some kind of silly workaround, which solves symptoms. I am
sending it to you only for information.
