I've been lurking on this thread a bit, but now that Till calls me I
guess I've got respond.

Several bug reports on this issue have been filed. See
The issue was fixed in the latest releases of sane-backends (1.0.17)
and iscan (1.18.0).

The CUPS backend is part of PIPS (iscan only does the scanning part of
the all-in-ones). The PIPS packages contain non-free software but I'm
not sure whether the CUPS backend part uses it. Me goes checking ....
All the sources for the ekplp CUPS backend are GPL'd with an exception
to link against EAPL'd libraries but the exception is not exercised.
# That is, it doesn't link against EAPL'd libraries.
FYI, the EAPL is a LGPL compatible license that allows for releasing
non-free components used by our software. Details at:

Someone already did. See:
The kernel folks blame SANE ;-)
