Blank page after "move to junk"

On a fresh install of Drupal 6 with ctools 1.3 and junk 1.0, Junk fails to work. After clicking the "Move to Junk" folder, a blank page is returned. I followed all of the instructions in INSTALL.txt, and did a fresh install of everything to test.

Apache error_log shows the following:
