I'm also experiencing the same problem with my Brother HL-L2390DW
printer, which includes a scanner function. Running `scanimage -L` from
sane-utils 1.3.1-3+b1, displays a HTML page in addition to real output.
Furthermore, performing an actual scan does not work; a HTML page is
displayed and nothing is scanned. The scan command is:
scanimage --mode color --resolution 300 --format=jpeg -o output.jpg
Downgrading libsane-common, libsane1, and sane-utils to last stable
version (1.2.1-2) fixes all of the above problems. No HTML page is
displayed and the actual scan works perfectly.
This is a regression in 1.3.1-3+b1.
