Summary: scanner cannot bring up TWAIN GUI
           Product: Wine
           Version: 0.9.43.
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: download
          Severity: enhancement
          Priority: P2
         Component: wine-misc
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I tried using a Canon N1240U scanner in Wine. This scanner works with
sane.

Whenever I try to scan an image, it tries to bring up a TWAIN GUI but fails
with a segfault. This occurs in both Irfanview and Picasa.

With Irfanview, goto File -> Acquire/batch scanning, and hit ok in the dialog
box. (You can get past bug 9404 by removing gphoto2.ds.so)

With Picasa, do an import and select the scanner from the list of sources.
(select device)

There is no backtrace from the segfault, but I tracked it down to
psane_control_option() in create_item() in dlls/sane.ds/ui.c.
