xsane manages to change resolution.

Choosing gray gives an I/O error.

Choosing a smaller region gives a SIGABRT...

Trying gnomescan (flegita) gives the *same* error, so this might be
libsane....

*** stack smashing detected ***: flegita terminated
Avbruten (SIGABRT) (core dumped)

with libsane-dbg installed (I'm on Ubuntu Feisty), I get the following
backtrace from xsane:

Actually, I got a cropped image from flegita once, probably by sheer
luck.

Next steps?
