uploaded files are randomly not being attached, nor can they be previewed
despite the upload confirmation. included is a screen shot of the
composition window after uploading the file where the preview fails
(preview shows blank and the file does not actually get sent with the
message, though the information in the compose window says the file should
be successfully attached). we've modified the logging system to narrow down
the source of the problem. this is the output from a failed attempt:

rebooting the machines seems to 'fix' the problem temporarily, but it
shows up again and now it seems to occur more frequently. we thought it
might have been a PEAR issue but the problem occurs on the latest version
as well.

one other thing to note is on subsequent testing we found that if a second
file is uploaded in the same message as one that has already failed (not
showing in preview) the second file appears as attachment number 1 with the
original attachment now gone.
