The Pixma backend is running with and without this patch on my 64-bit Ubuntu 12.04. I have no problems with any linux kernel (tested with kernel version 3.2.0 and 3.8.0) without this patch. 'cause my ppa is affected, I would like to have an official patch for this issue. Somebody who is involved in coding scanimage should tell something about this. I have no idea about the usage/need of the optind parameter in the getopt library. Cheers, Rolf
