[horde] Apache's error log filling up since upgrade

[Daniel A. Ramaley]

Since using the patches today to upgrade from Horde 3.0.9 to 3.1 and Imp 
4.0.4 to 4.1 i have noticed a large number of errors in Apache's log 
file. The upgrade patches applied cleanly without problems. The server 
is running Red Hat Enterprise Linux 4 with Apache 2.0.52 and PHP 4.3.9. 
I have included below a one-line sample of each error message. Is there 
a configuration change that i need to make for the new version?

Just out of curiosity i decided to do a search of the entire Horde 
directory for some of the undefined indices. They appear to be limited 
to just a few files:

$ find /var/www/html/horde -exec grep --count -H imap_server {} \; \
  | grep -v ':0$'
/var/www/html/horde/imp/lib/Search.php:1
/var/www/html/horde/imp/lib/Session.php:5
/var/www/html/horde/imp/lib/IMAP/Tree.php:1
/var/www/html/horde/imp/lib/IMAP.php:2

$ find /var/www/html/horde -exec grep --count -H notepadavail {} \; \
  | grep -v ':0$'
/var/www/html/horde/imp/lib/IMP.php:1
/var/www/html/horde/imp/lib/Session.php:2
