Package: libsane1
Version: 1.0.32-4
Severity: grave
Justification: renders package unusable

Dear Maintainer,

I've upgraded libsane1 package from 1.0.31-4.1 to 1.0.32-4 and my Epson
Perfection 164SU stopped working.
I tried to debug the issue with:

~$ SANE_DEBUG_EPSON2=255 scanimage --device=epson2:libusb:006:011 --format=jpeg
--output-file=./test.jpg

and I discoverd this error:
...
[00:15:42.111491] [epson2] setting focus failed
scanimage: sane_start: Operation not supported
...

I think that this error is related to this changelog of "SANE Backends 1.0.32":
epson2: adds autofocus support for devices that support it (!531)
Info:

Downgrading to libsane1 1.0.31-4.1 solve the issue.
