I think the error is not linked to the memory error message. There is a nasty bug on actual version that leads to a memory error when duplicating slides. To resolve it, you have to remove the pictures on the slide that should appear just after the error, then put the image back, and it should work.
I know this bug is very annoying and I will release the next version 1.4.2 that will correct it as soon as possible.
Yes it is possible.
