Description of Problem:
    Xsane in "save" mode issues a cryptic error messages and refuses to scan to
a file:

        Error during save: Could not create secure file (may be a link does
exist): (null)

Version-Release number of selected component (if applicable):
    xsane-0.82-3.1

How Reproducible:
    100%, in lineart and color modes (other modes not tested)

Steps to Reproduce:
1.  invoke xsane
2.  select the HP scanner (rather than V4L)
3.  position the bogus window
4.  position the command window
5.  select "Save" mode
6.  click on the "Start" button
7.  watch the "Error during save..." box appear

Actual Results:
    An error box appears:

        Error during save: Could not create secure file (may be a link does
exist): (null)

    At the least, the error message should be less cryptic, even if it is an
operator
    error situation.

Expected Results:
    Xsane should continue to scan.

Additional Information:
    I have successfully scanned to a file, using "Save" mode, in the past.  I'm
fairly
    certain some of that past successful experience was with the present version
    of xsane, but I might be mistaken on that.  The scanner is an HP Scanjet
6300C
    over USB, using a five-port PCI USB adapter card of unknown make.  Other USB
    functions appear to be fine, including printing on two different printers. 
XSane can
    successfully copy using "Copy" mode, but it has the same error problem when
    used from the Gimp's acquire menu.
