Title:
  saned not working in Utopic or Vivid

Status in SANE-backends - Backends for SANE:
  Unknown
Status in sane-backends package in Ubuntu:
  Triaged

Bug description:
  Following https://help.ubuntu.com/community/SaneDaemonTutorial worked
  in Trusty with my HP OfficeJet 5610v All-in-one plugged into a USB 2.0
  port.

  However, in Utopic, network scanning does not work. For example, in Windows 8.1 with SaneTwain 1.3.6, it used to work. Now it pops up a window:
  Error
  No devices found on backend.

  However, in the Device drop down it notes:
  hpaio:/usb/Officejet_5600_series?serial=XXXXXXXXXXXXXX

  Ubuntu 15.04 client with either xsane or simple-scan doesn't find anything. Running the following from a terminal results in either a crash or no SANE devices found as per https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1442960 :
  scanimage 192.168.1.15
  scanimage: no SANE devices found

  scanimage 192.168.1.15
  *** Error in `scanimage': double free or corruption (!prev): 0x00007f5a939fff10 ***

  The scanner works fine locally on the server via simple-scan.
