	Hello,

	providing debugging log of the problematic version would help getting a 
useful answer. The Canon LiDE 35 is supported by the genesys backend. So to 
produce debug log, in a shell window, raise the debug level and launch xsane 
with messages redirected to a log file by the following commands:

export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_GL841=255
xsane 2>debug.log

	Do a small 600 dpi scan, then a 2400 one. Send the debug.log file 
(compressed) to the list so we could have a look and get an idea of what is 
going on.

	The exact version number of the SANE package that worked correctly is also 
interesting, so changes between versions could be analyzed in search for the 
problem.

Regards,
	Stef
