After updating to 1.2.3 and modifying the code to use django 1.0 (I
was using zipimport to use 1.0 before), I occassionally get this
exception. Once I get it, the only way to make it go away is to
restart the dev server. Could it be that making changes while dev
server is running is triggering some sort of reload that ignores the
use_library stuff?
