It also happens as root. I diffed the log files
and can't see anything special. If I may take
the liberty, I send the new log file again --
just to be sure, that I didn't overlook some-
thing.

=|. I was looking for something like sane-
backends . . . libsane is already installed
in version 1.0.12.

That's what I already did before asking my
question. I couldn't find anything. From the
log file you can exclude, that the scanner is
defect!?!

Yeah, it *did* too on my system since
beginning of the week -- last friday I
just scanned a lot . . .

*wondering what's going wrong*
