Software Error while using Whine option in Bugzilla 3.4

[skumar]

Hi All,

I have upgraded Bugzilla from 3.0 to 3.4. I am getting one Software Error Message as : Can't use an undefined value as an ARRAY reference at /var/www/bugzilla-3.4.4/editwhines.cgi line 385." while clicking on "Whine" option as Bugzilla Admin user.

I checked editwhines.cgi and line no. 385 (highlighted in Bold) displays as below:

elsif ($mailto_type == MAILTO_GROUP) {
$sth = $dbh->prepare("SELECT name FROM groups WHERE id=?");
$sth->execute($row->[3]);
$mailto = $sth->fetch->[0];
$mailto = "" unless Bugzilla::Group::ValidateGroupName(
$mailto, ($user));

I have verified above file with other Bugzilla 3.4 installation file and it matches fully, but unfortunately I am getting software error message while trying to configure "Whine" in Bugzilla.

Reproducible: Always

Steps to Reproduce:
1.Login Bugzilla using admin password
2.Select "Administration" and then click "Whining"
(http://server-name/bugzilla/editwhines.cgi)

Actual Results:
It displays error message as : "Software Error : Can't use an undefined value as an ARRAY reference at /var/www/bugzilla-3.4.4/editwhines.cgi line 385."

Expected Results:
it should take user to editwhines.cgi page to display option to add/remove
whine event-schedule and whine event-search without any error message.
