Image upload "undefined" occurs randomly and frequently

[Paul Egli]

I'm coming across an issue where it seems completely random whether a thumbnail and filename will load on the clipboard after uploading several JPEG images or no image at all and "undefined" instead of the filename. I've been experimenting with the same four images and everyone of them has successfully rendered a thumbnail and image name for me at some point during testing - just not consistently. Has anyone experienced a similar problem?

While this doesn't seem like a pillow issue, I uninstalled PIL and pillow, and re-installed django-filer (so that it could pick it's own image dependencies) and result of the pillow install (PIL SETUP SUMMARY) is below. I have installed the required binaries pillow defines (sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk).
