[sane-devel] Segmentation fault: 11

[Fred Leason]

I am on Mac OS X Lion 7.4
I am using the macports version of the software

I have a Canon Pixma MP970

This used to work via gimp.  When I invoke the scanner, xsane starts up and I could easily scan and edit images in gimp.
No longer.  Now I get the xsane screen that says scanning for scanner.  It disappears after several seconds.

So I followed the instructions on the FAQ.  Here is the output:

So it sees the scanner and then dies.  

Here is output from

which recognizes the scanner among other things.

and

> 05:09 PM ~ $ scanimage -L
> device `pixma:04A91726_23464B' is a CANON Canon Pixma MP970 multi-function peripheral
> Segmentation fault: 11

and the "scanimage -d test:0" worked fine.

This has not worked for months.  Any ideas?
