Sometime pages fail to load properly and display a blank page

[k3nt-1]

Binary package hint: firefox-3.5

Steps to reproduce:
Go to to http://peprtree.com
Expected results:
A page is displayed with an image and some text
What happens:
Sometime the page displays correctly, and sometimes nothing is displayed (blank page and blank "view page source" page.

I own the server and doubled checked everything from config to logs. Nothing there and other sites served by the same web server works flawlessly.
I checked with epiphany browser and was not able to reproduce the bug.
The page is valid HTML 4.01 strict: http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fpeprtree.com%2F
Problem was reproduced on a second computer (running another version of Firefox 3.5 on ubuntu 9.04)

Problem cannot be reproduced easily but pressing ctrl + F5 a few times should trigger it.

I'm aware this might be an apache bug or misconfiguration on the server side, but I can provide vhosts configuration to track down the problem if required.
