@Dmitry
Did you once read any of my comments? I know that Wine just passes the file io requests to the kernel. That is the very problem and you named it as well. Linux kernel has different io semantics than Windows, at least concerning sparse files.
Which makes this a kernel/fs bug, not a Wine bug.
