IMP setup error (on the right mailing list)

[Ry Jones]

I asked some time ago but got no responses, so I'll ask again. (I guess it 
helps to ask on the right mailing list! D'oh!)

I am installing IMP and HORDE and when I test the sessions
(test.php3?mode=phplib-horde) I get this error:

Warning: variable key 1 doesn't exist in /usr/local/apache/php/ct_shm.inc on 
line 79

What am I doing wrong? I broke down and installed the RPMS instead of the 
tarballs and it still doesn't work.
TIA,
Ry
