**********

it "used to work". i could add items w/o problems, but then i deleted an 
entire (misconfigured) collection to start from scratch, and now i can't 
submit. dspace version is 1.2-beta2 from sourceforge, os is linux (suse 
9.1 with 2.6.5 kernel on dual ia32).

any ideas welcome, tia,

jörn
