Thanks David for investigating.
I managed to manually patch setrefs.c according to your patchset on a Linux test installation.
The query/explain query (without the unneeded XML-stuff) runs fine now, no more error!
I will try to reactivate my Windows development environment, but the error seems not to be related to operating system version.
Many thanks for your quick reaction!
