Yes and no.  I ended up doing all my scanning with the 
command-line ‘scanimage’ (and adding PNG support to it), and 
cropping with the GIMP where needed.  Not ideal but it works 
reliably.

Simple Scan doesn't.  It recognises my scanner (not a difficult 
job and SANE's to boot), but actually scanning (slowly) produces a 
black page, without moving the scanner head at all.

Sometimes Simple Scan will suddenly work *after* I've scanned 
something with ‘scanimage’ directly.  Other times, it still won't.

XSANE (which isn't on master yet) just freezes as soon as I hit 
the ‘Scan’ button.

Both GUIs worked fine with network scanners.

Interesting.  Here, being root makes no difference (and I can scan 
without sudo).

Kind regards,
