steps:
1. open proclaim
2. in new or existing presentation click 'add items;
3. click 'import powerpoint'
4. select any pptx (i've tried several different pptx files)
( clicking local check box seems to not affect outcome)
5. click 'add'
results: proclaim PREPARING spinny logo is displayed, and within a minute or so it crashes.
I've included a pptx file that it definitely crashes on as well ...
