At least in LC 5.0.1. Attempting to Print to PDF with any graphic effect applied to an object in the area to be printed results in a blank PDF and causes the app to quit. As a workaround, either make such objects invisible or remove all graphic effects prior to printing to a PDF.
Thanks to John from MobGUI (indispensable IMO) for finding this bug.
