I wrote a scanning program that uses the Sane library eight or nine years ago, and have been using it happily, since then. A couple of weeks ago, it occurred to me the machines to which the scanners are connected hadn't had their OSes upgraded in at least three years. Unfortunately, upgrading them broke my program, and I can't figure out why.

The scanners are Fujitsu fi-6770djs, with both document feeders and flatbeds. If we stick with the document feeders, everything is fine. If we scan on the flatbed, then switch back to the document feeder, sane_start returns SANE_STATUS_INVAL. Restarting the program resets everything and allows us to use the document feeder, again. Now, I know that when you use the document feeder, the page dimensions have to be specified with page-length/page-width, while the flatbed requires tl-x/tl-y/br-x/br-y, and my program accounts for that.

I tried moving some stuff around so all the options are set right before sane_start is called (rather than immediately after the user sets them), but that didn't help.

I tried previous versions of the Sane library, from 1.0.22 to 1.0.27; didn't help.

Here's the debug output:

If anyone can point me in a direction that might help, it would be greatly appreciated.

Thanks

You've cut out a bit too much of the log for me to see what is going
on. Perhaps compress a full log and send it to me directly.
