Package: xsane
Version: 0.997-2ubuntu3
I have reported the following bug to the XSane bug tracker at
https://alioth.debian.org/tracker/index.php?func=detail&aid=313503 but
it was suggested that I also report it here as the upstream project has
not made a release in over a year.
----
When scanning to the viewing window then saving a file, changes to the
file type cause the filename to fill with spurious characters, the
system to report an 'Invalid file name' then 'A fatal error occured
while running the scanning application'.
Environment: XSane 0.997 on Ubuntu 10.10.
Issue can be duplicated as follows:
* Start XSane.
* In main control window select Type as 'JPEG'.
* In main control window select Target as 'Viewer'.
* Carry out scan, setting other options if necessary.
* The Viewer window should open.
* Select File->Save image.
* In the Type drop-down chooser, select 'PDF'. Observe that the Name
textbox changes appropriately.
* In the Type drop-down chooser select 'by ext'. Observer that the
non-printable text is entered into the Name textbox.
Of course, as a workaround it is possible to manually remove the
non-printable text and enter a new filename in the Name textbox.
----
The problem was traced to xsane 0.997 source code, file:
xsane-back-gtk.c, function: xsane_back_gtk_filetype2_callback.
Code in this function will determine the new name for a file when a file
extension is chosen from the Type drop-drown chooser. When 'by ext' is
chosen no code is executed to populate the string pointed to by the
filename, leaving uninitialised memory at this location. The
uninitialised memory is later copied back to the UI.
The attached patch against XSane 0.998
(http://www.xsane.org/download/xsane-0.998.tar.gz) resolves this issue.
