The problem appears to be a bug that occasionally causes the exported files to be empty when export settings haven't been set. Just now, I tried to export a sizable deck file, got an empty file, but then then viewed the export settings and hit okay (i.e., used the default settings). WHen I tried again, the export was successful.
