Hi there, looks like there is a bug here. please advise?

I have a fresh install of joomla 2.5.4 and am using the latest K2 just downloded yesterday and installed.

Error message:
Notice: Undefined variable: children in /home/(xxxx)/public_html/modules/mod_k2_login/helper.php on line 94



any ideas? thanks

FIX FOUND!
I have a friend from www.blastchat.com , he is a good code guy and was able to fix it with this fix. Thanks peter from blastchat.com (he makes a great joomla chat component)

open up "helper.php" path.. modules/mod_k2_login/helper.php
in getMenu function Iplaced following code at the beginning:

if (!isset($children)) {
$children = array();
}
