[horde] Horde/IMP problems after system upgrade

[Anders Norrbring]

I've changed my hardware and upgraded the base system to latest Apache 
and PHP5.
Now I'm having problems with my old Horde and IMP installation, I need 
it to run while I install the latest versions.

Horde is v2.2.5
IMP is v3.2.3

The problem is that I log in, click on an e-mail to open it, and the 
message texts doesn't show, only the header info.
I can d/l the mail though.

In the Apache error log, this shows up:

Can I temporary fix this while I'm setting up the new system in parallell?
