I discovered that I was able to easily fix a crash that occurred when dismissing the export options dialog, so I updated the Mac version to 4.2.1 with that fix. It's available from the links above. This is a Mac-only fix to a Mac-only problem, so the Windows and Qt versions remain unaffected.
Orion, I think you reported on this a while ago with LDView 4.2 Beta 1.
