Since upgrading to 12.10 (Xubuntu), Simple Scan is not working anymore.

I got scanning working with Xsane, but only if Simple Scan has not run before. Otherwise I have to restart the printer/scanner (HP OfficeJet J5783).

In kernel.log I see:

kernel: [ 1214.120964] usb 2-1.4: >usbfs: process 4412 (simple-scan) did not claim interface 2 before use

and in syslog

simple-scan: io/hpmud/dot4.c 172: unable to read Dot4ReverseCmd header: No data available

Any ideas?
