Since upgrading to the latest PEAR versions yesterday, I see the following message being logged quite regularly: WARN: HORDE [horde] PHP ERROR: min(): When only one parameter is given, it must be an array [pid 14248 on line 262 of "/usr/share/php5/PEAR/Horde/ActiveSync/Folder/Imap.php"] Is this something to worry about, or just log noise?
