[sane-devel] Canon PIXMA 490 Seg Fault

[Atom Mac]

Hello everyone!

I've been attempting to get the "Automatic Document Feeder" to work with
my Canon PIXMA 490 but after a 1-2 minute delay, `scanimage` outputs a
"Segmentation Fault" error (which no details).  Below are the full
inputs and outputs involved.  Note that scanning works fine with the
`Flatbed` source; just not the `Automatic Document Feeder` source.

## Input

scanimage \
        --device=pixma:04A91787_77BF9D \
        --source="Automatic Document Feeder" \
        --batch=out%d.png \
        --format=png \
        --mode=Gray \
        -v

## Output

Scanning infinity pages, incrementing by 1, numbering from 1
Scanning page 1
Segmentation fault

## System Info
Raspberry Pi 3
Alpine Linux 3.17.3

Any help would be greatly appreciated!
