[Zope] broken images in management interface

Hello, I tried to install the WMF tasks/help desk product mentioned earlier in the list, and after doing it some of the images in the management interface appear broken. Files like http://localhost:8080/misc_/OFSP/dtmlmethod.gif are not found. Others like http://localhost:8080/p_/ControlPanel_icon do appear. I have even reinstalled the zope package (I am using debian) but the images are still broken. What could have caused this and how can I fix it?
