[imp] IMP not compatible with Kronolith and Turba

[Law Albert]

Hi all,

I am installing Horde (IMP + Kronolith + Turba) and my installaion has a 
very strange behaviour:

1. When only IMP is enabled, no problem

2. When only Kronolith and Turba is enabled, no problem

3. If IMP + either Kronolith or Turba, or both, then:
 a. The sidebar on left will disappear
 b. When I click Adminstration -> Setup -> all config pages ok, except 
Horde config page (blank screen)


Here is my OS and Horde setting:

OS: Fefora Core 4
PHP: 5.0.4-10.5
mySQL: 4.1.20-1.FC4.1
Horde: 3.1.3
IMP: 4.1.3
Kronolith: 2.1.2
Turba: 2.1.2

Please let me know if I need to provide what information. Thanks for all 
your help!!

Regards,

Bert.
