Are you already running aolserver cvs head or something close to that? The changes to init.tcl were only made recently to my knowledge (Dec '11).
I'll see if I can get the problem to reproduce with project manager. In the meantime, you could try commenting out the errant code - init.tcl:594 which is
::append _import [::list rename [::namespace current]::[::namespace tail $_orig] $_cmnd] \n
