This is really messed up:

206e6ed094c080be903b154ea3d016cc226feb89 is the first bad commit

    Adding new kodakaio backend


The commit 206e6e is REALLY the first bad one (the one where it starts
segfaulting). Curiously there are no changes in epson2 in there.

I confirmed that the predecessor,
df6a8ef89dbd061fb383722ddd6272e07fc468b3, is working (somewhat). At
least it is NOT segfaulting, but displaying in the end:

[...]
Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.

List of available devices:
libusb: 0.000000 error [do_close] Device handle closed while transfer
was still being processed, but the device is still connected as far as
we know
libusb: 0.000043 error [do_close] A cancellation hasn't even been
scheduled on the transfer for which the device is closing

(then it hangs indefinitely, as described before)

No idea what the hell is going on here.

Best regards,
Johannes
