`scanimage -h' core dumps with Kodak ESP2510 scanner

Running "scanimage -h" on Ubuntu 17.10 with my Kodak ESP5210 returns:

...
Options specific to device `kodakaio:net:192.168.0.12?model=0x4041':
  Standard:
    --mode Color|Gray|Lineart [Color]
        Selects the scan mode (e.g., lineart, monochrome, or color).
    --threshold 0..100% (in steps of 1) [50]
        Select minimum-brightness to get a white point
    --depth 8 [inactive]
        Number of bits per sample, typical values are 1 for "line-art" and 8
        for multibit scans.
    --resolution 75|150|300|600dpi [75]
        Sets the resolution of the scanned image.
Segmentation fault (core dumped)

Here's the core dump:

[Thread debugging using libthread_db enabled]

I imagine this causes the error I get when I try to scan in gscan2pdf:
"Error retrieving scanner options: error getting option 6: Invalid argument"
(I get a similar error from xsane).
