Comment 6 for bug 974347

More information: I think the error message was a red herring. It appears to be an artifiact of the initial device probe and vanishes if I uninstall all the HPLIP related packages.

I'm growing suspicious of something in the SANE initialization process. I discovered by accident that if I run a scan using Xsane, exit that program and re-start gscan2pdf it springs into life and I can run sheetfeeder scans. I think this is why updating my version of gscan2pdf appeared to fix things last time around. I had tried with Xsane after fruitless attempts using gscan2pdf and never went back to the latter until after I upgraded.
