[imp] all messages 0kb

[Liam Hoekenga]

Hey guys -

We're just starting to experiment with deploying imp on linux.  We're using
Horde 2.2.1, IMP 3.2 RC3 and Turba 1.2RC1 w/ Apache 1.3.27, PHP 4.2.3 on Gentoo
1.4RC2.

It seems nice and speedy (when php isn't segfaulting), but I noticed today that
all of the message sizes are showing up as 0kb in mailbox.php. It's a copy of
the horde folder we've got on our solaris test box, and it works fine there. 
We're currently trying IMAP 2001a.

Any ideas?

Liam
