Bug#758596: xsane: multipage project fails to save output file

["S. Roy" <subhashisroy2000@yahoo.co.in>]

Package: xsane
Version: 0.998-3+b1
Severity: important

I am using a Canon Lide 110 scanner with my laptop through USB.
This works okay while saving Single page scanns.
I then selected the Multipage mode, it asks for creating the project,
which I created.
Then, I tried using both Color and Lineart scans.
It provides options for the Multipage document filetype, and I selected PDF,
which is the default.
I scanned both sides of a page, and it showed
image-0001
image-0002
After that I hit the Save multipage file.
It Shows 'Saving file', and it stops there for ever.
I waited for ~15 minutes, and it never showed anything more.
It does create a 'multipageproject.pdf', which is just 145 bytes, but does not
contain
the proper data.

I have also tried the following before trying to save:
select image-0001, and then hit Edit image, which could not show the image,
and complained no 'image-0001.pnm' file found.
However, the actual scanned pages are visible in '/tmp' with filenames like:
'xsane-conversion-genesys:libusb:003:018.ppm-1001-aDUWew'
