I have switched over to IMP 2.3.6 and hore 1.3.3 and I'm running the
latest cvs of PHP (4.0.7).  When I login to my mailbox I get 
Warning: Unknown list entry type in request shutdown (0) in
/usr/httpd/html/horde/lib/Horde.php on line 240

Warning: Unknown list entry type in request shutdown (0) in

Warning: Unknown list entry type in request shutdown (0) in
/usr/httpd/html/horde/imp/lib/IMP.php on line 292

Then, wehn trying to open a message, I get
