[sane-devel] still segmentation fault on MP900, MP950

[Nicolas Martin]

Hopefully, code and declarations for those 2 old models, MP900 and
MP950, is not part of the git version, probably this is from a test
version you're currently using for debugging. 

Those 2 Pixma models are more than 5 years old, so probably not
strategic to have them supported for the next Sane release, as nobody
asked for support to these models, since I'm working on the pixma
backend.

Let us know anyway when this issue will be fixed, and when these models
will be ready for support.
