[kronolith] Errors after CVS update

[Rick Emery]

I did a cvs update this afternoon, and everything went fine.

I did another update tonight and get the following errors at the top of my
kronolith screen, but everything seems to display fine below the errors. If I
display calendar information on the summary screen, I get the top two errors;
they disappear if I remove calendar info from the summary.

Notice: argument passed to unserialize() is not an string in
/var/www/html/horde/kronolith/lib/base.php on line 109

Warning: Invalid argument supplied for foreach() in
/var/www/html/horde/kronolith/lib/base.php on line 111

Notice: argument passed to unserialize() is not an string in
/var/www/html/horde/kronolith/menu.php on line 28

I backed out the only commit I remember during the day related to kronolith
(replaced !empty with isset) with no change.

Line 109 in my base.php is:
$_all = unserialize($GLOBALS['prefs']->getValue('remote_cals'));

I don't have any remote calendars.

Thanks in advance for any help,
Rick
