Hans-Peter? Your thoughts? I've forgot if someone mentioned whether we have a test-case in our test-suite for this feature. If we don't, then 3; removal.

Then it *might* be worth the effort fixing that and additional test-coverage (depending on the person stepping up...) but 3 is IMHO still an arguably sane option. brgds, H-P
