Problem with Horde on 3.2.1, even with smaller attachments

[Skip Morse]

Hi All...

Still sorting out some issues on the test system before moving forward
with the production system...

Currently I'm getting some weirdness when trying to view emails with
attachments.  Even some as large as 190K sometimes just seem to not
load in the preview and then if I click (or double click?) to open
them I get an error 500.

I've tried adjusting the memory settings in the php.ini file and I
thought that helped, but I guess not... currently I have it set to
256M for the amount allowed for php script, and increased some other
options per one of the suggests I found on the mailing list.  It still
seems to give me that same issue.  I thought it was a problem with
addressing it by IP, so I edited my hosts file so it would point to my
test system with the proper host name and that didn't help.

The lines below are from the php errors log.  I get a lot of the first
line, then after those it will be the last 2 lines.

[04-Jun-2011 00:26:35] PHP Warning:  register_shutdown_function() [<a
href='function.register-shutdown-function'>function.register-shutdown-function</a>]:
Invalid shutdown callback 'Array' passed in

So, not sure if that is normal or not, any thoughts or places to look?

Thanks,
