Hi,

After thinking a bit, it turned out this might not an really Ubuntu issue, as the crash seems to be originates from

$ dpkg -S libsane-smfp
suld-driver2-1.00.36: /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1
suld-driver2-1.00.36: /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1.0.1
suld-driver2-1.00.36: /usr/lib/sane/libsane-smfp.so.1
suld-driver2-1.00.36: /usr/lib/sane/libsane-smfp.so
suld-driver2-1.00.36: /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so
suld-driver2-1.00.36: /usr/lib/sane/libsane-smfp.so.1.0.1

which is an external package.... however, the same package / sane driver was working fine with the previous ubuntu's i wonder what has changed...
