Is this correct?
If so, let me build and test.
Building it already as we speak, but it would be nice if you could
confirm I'm actually testing the right thing.
Though, wouldn't it be good to repro and get a core file as well?
Or would the test of this commit narrow down the possibilities as well?
Thanks,

Reinoud.
