I have been trying for six hours to get XSANE to
work with my Canon MP 970 printer. The programme installed and runs
normally, it recognises the printer, but when I ask for a preview,
nothing happens. The software does not freeze - the preview can be
cancelled, and all the rest of the programme still works - but no
scanned image appears, despite a five minute wait before cancellation.
Simple scan and scan2pdf both work, but neither are as
sophisticated as XSANE, nor have the features I want.
I have visited
"file:///usr/share/sane/xsane/doc/sane-problems-doc.html", and, although
my specific problem is not mentioned, I have run through most of the
remotely applicable suggestions without success. The back end is there,
SANE is there, the scanner shows up correctly in Terminal and I have
commented out all back ends except those for Canon and Pixma in
sane.d/dll.conf. I tried "$find / -name "*sane*" | less" as root, but
nothing appeared except a blinking cursor, despite me waiting ten
minutes or so.

Does anyone have any ideas??
Postscript - After writing this, I tried gdb xscanimage
after the frontend returned:
for the third time, with the the following result:
Starting program: /usr/bin/xscanimage

Before I ran the command "backtrace", there was a limited GUI front end
returned, and I successfully obtained a preview, and was able to do a
scan, and save it. Weird??
