Tim and I have been looking at this offline. The significance of lk 2.3.43 was the addition of a new sg driver that has an additional interface. Recent versions of SANE use that newer sg interface. The problem that Tim reported seemed to be caused by timeouts ** resulting in scsi bus resets. Anyway the problem seems to disappear with the recently released SANE 1.0.4 . [The original report was based on SANE 1.0.3 and earlier.]
There is also a problem report with the SnapScan 1236 <--> aha152x combination also based on SANE 1.0.3 . This one is looking like an "uninitialized errno" bug fixed in SANE 1.0.4 .
** SANE's newer sg interface shortens the per command timeout from 10 minutes to 10 seconds. Most other OSes interfaces in SANE have a timeout value of 1 minute or more. I suspect 10 seconds may be too short.
