I can confirm this bug. When using text mode, simple-scan shows the
scanned page correctly, but when saving as PDF, evince renders it
completely empty.
I attach a test scan, with my Canon LiDE 30. This worked fine in lucid
and early maverick, it might be correlated to the switching to 4 gray
levels?
$ evince /tmp/test.pdf

(not sure whether the error messages are related)
The top part is really blank, I scanned a post card from a magazine.
