[imp] attachments not quite working

[jlewis at lewis.org]

For some reason, on one of our imp installations, when we try attaching a
file in the compose window, after clicking on attach, the window refreshes
with the text "Added an attachment" at the top of the window, but the
attached filename does not display at the bottom of the window under
"Attachments" and the message sent has no attachment.

I've been searching the mailing list archives, and I see this is pretty
much a FAQ, but I've verified all the usual suspects that I'm aware of.

The file is uploaded to the web server in /var/tmp.  php.ini's
upload_tmp_dir = /var/tmp
horde/config/horde.php's $conf['tmpdir'] = '/var/tmp/';

The system is Red Hat 8.0, Red Hat's 4.2.2-8.0.8.  I'm not seeing any
errors either in the apache error_log or syslog, during any part of the
compose/attach/send process.  My test attachment file (/etc/hosts) is
quite small (<200 bytes).
