Hello...
I am the author of the apple backend.
Unfortunately I cannot help for two reasons
-I don't have spare time. Maybe after july 8.
-I don't have the device. The orginal backend was written for sane 0.69
and for
the AppleScanner (4bit 16shades of gray). Yes the two scanner are
similar. Yes the same backend should be used for both. Yes there will be
support when I find time and somebody to help with the debugging.
For the mean time could you possibly turn on debugging on so we can get
a clue about the crash. Try set the env variable SANE_DEBUG_APPLE to 255
or something like this. Check the mustek man page and change the MUSTEK
to APPLE.
