--- Comment #12 from Sebastian Lackner sebastian@fds-team.de --- Thanks for testing :)
My patch (including some additional tests) was submitted to wine-patches: http://source.winehq.org/patches/data/105118
BTW: As it turns out this problem can even be reproduced with the wine test suite - it just wasn't noticed because the tests didn't explicitly check the resource directory virtual address.
