--- Comment #11 from Jeremy White jwhite@codeweavers.com 2009-02-25 17:16:22 --- You don't appear to be running a current git version of Wine; you have a log message that should correspond to current line 408 in dlls/sane.ds/ds_image.c, but it's missing the bpl= notice. (And there is a new FIXME right abouve that you should have gotten, which I don't see).
Could you check that? Also, if you shift /etc/sane.d/test.conf to Color instead of Gray I would expect you to see different results; the FIXME says that Gray isn't supported yet :-/. (But it shouldn't crash either way).
