When I upload a file using PHP, it seems to break sessions.
Hi Dan,
No direct experience of this myself, but I was researching this functionality
and came across the below recent bug report in the archives. I think it speaks
to your issue. I also included my post to the php-dev list, in case your
interested. (My response, followed by original bug report below.)

Crashes (signal 11) on file upload using multipart form data.
Worked with 4.0.4pl1, haven't tried 4.0.5, crashed with 4.0.6 and latest
CVS since.
Hello,
Has this been addressed at all?
In any case, when the PHP multipart form handling functions worked properly
(v4.04, etc.) , how did they expect the file data to be encoded?
Does PHP expect it to be encoded as binary? Does it handle and respond to a
'Content-transfer-encoding:' header for each sub-part? Or, does PHP require the
data to perhaps be base64 encoded as required by SMTP transport, even though
HTTP is being used? I'm thinking that maybe some other MIME handlers designed
for email are being re-purposed in PHP here and cannot properly handle binary
data.
Thanks!
