Description:
sane frontends (scanimage, xsane, etc.) started to provide corrupted image data sometime after Oct. 8. I am unable to track the issue down to an update. I am using the hp5400 backend (refer to the attached image of a blank plastic sheet), though I have also tried using a different scanner which is known to work, which requires the niash backend. With this backend, sane yielded a different corruption pattern, in particular, vertical streaking of the correct image, rather than noise.

A cursory search of the Arch Linux bugtracker, WWW forum, and arch-general mailing list, sane's sane-devel mailing list and bugtracker, and the WWW, has not revealed any hits.

Additional info:
* package version(s)
sane 1.0.23-1

* config and/or log files etc.
$ scanimage -vv >test.pnm
scanimage: scanning image of size 630x724 pixels at 24 bits/pixel
scanimage: acquiring RGB frame
scanimage: min/max graylevel value = 0/159
scanimage: read 1368360 bytes in total
Closing device
Calling sane_exit
scanimage: finished

Steps to reproduce:
1. scan using any settings with a sane frontend (e.g., invoke "scanimage -vv >test.pnm")
