Looks like it's from brscan4-0.4.11-1.x86_64, which is a proprietary
part of the Brother scanner driver. That would explain why others
aren't seeing it.
I'm going to remove that and attempt to configure the opensource
driver. I did this not long ago but have recently installed a new all-
in-one printer/scanner, so that looks like the culprit.
