Description of problem:
When creating a new BZ, I cannot attach a file to the BZ.  I fill in all the
fields in the "Create Attachment" section of the BZ but when I click "Commit"
and look at the new BZ, my attachment isn't there.  After the BZ is created, I
can attach a file.

This may be related to BZ 197096; I often have to re-login to Bugzilla and it's
possible that the attachment information is lost when I have to enter my name &
password again.  (Fortunately the rest of the BZ text isn't lost, but just in
case I've started to copy-and-paste the text to a local file before hitting Commit.)

Version-Release number of selected component (if applicable):
Bugzilla 2.18-rh

How reproducible:
Very often

Steps to Reproduce:
1. Create a new BZ
2. Try to attach a file
3. Click Commit button
  
Actual results:
The file was not attached to the BZ

Expected results:
The file should be attached to the BZ
