This looks very similar to http://bugs.debian.org/498532
Like in http://bugs.debian.org/585887 I can press "Preview" in xsane and
that works. However as soon as I press "Scan" I get the "Operation was
cancelled" popup.
As in #498532 both xscaneimage and quiteinsane can scan without
percievable problems. That would imply that the problem is either with
xsane itself or in the interaction of xsane and the backend and not with
the backends (since both xscaneimage and quiteinsane should be using those
same backends).
I also tried to install 1.0.21-7 from unstable and the result remained the
same.
My scanner is a Pixma MP600.
xsane worked under xsane under Ubuntu Lucid.
As suggested by Julien I started xsane with SANE_DEBUG_PIXMA=3. The output
is attached. There are three attachements:
* xsane-start which is the debug just from starting xsane
* xsane-preview which is all that came after xsane-start, when I pressed
"Preview"
* xsane-scan which is all that came after xsane-preview, when I pressed
"Scan"
Other than pressing "Preview" and "Scan" I did nothing else in the xsane
(no changing of settings or other).
Another suggestion of Julien was to "rm -r ~/.sane/xsane". Now:
* remove preferences, start, preview, scan -> "Operation canceled"
* remove preferences, start, scan -> works!!!
* leave preferences, start, preview, scan -> "Operation canceled"
* leave preferences, start, scan -> "Operation canceled"
!!!
I also installed libsane from experimental
(libsane_1.0.22~git1.0.21-157-g126c70d-1_amd64.deb), but xsane has the
same problem with it as with libsane from squeeze.
