Mine asks for a non-existant file with an odd character in it---a small o with a line under it--and hangs up Poser. But at least it is showing up in the Pose Library now. DAZ is still working on it, so I hope to have a working copy someday ;) Short answer: yes, there must be something odd about the item or it wouldn't hang up a newish iMac with lots of memory installed. And I've learned to my cost to bring Vicki3 in first, too. But it doesn't help with the MalePak, unfortunately.
