If you do this you also need to make the props array 1 entry bigger (increase
it from 4 to 5 entries). Before this patch there are max 3 properties added
and there needs to be an empty terminating property at the end (which
is what the memset is for). So before this patch props[] needs to have
4 entries (which it does) and thus after this patch props[] needs to
have 5 entire.s

Regards,

Thanks for pointing this out Hans! Didn't change it from 4->5 since we had only 4 properties, wasn't aware of the terminating property. Will update the patch.

Thanks again
