I'll have a look at this. Unfortunately serialization and @safe do not 
go well together due to https://issues.dlang.org/show_bug.cgi?id=16528 
so that currently manual (non-generic) workarounds are required, and 
there may be other similar issues lurking.

For the specific code, if possible, the easiest way to sidestep the 
error would be to use @safe or @trusted on those property functions.
