Bug Description
Attempting to scan via wifi from a Brother MFC-7860 DW fails; the scanner shows scanning but:
- no image appears in simple-scan.
- simple-scan consumes 100% CPU
- the ~/.cache/
This used to work perfectly and indeed the following provides an instant work-around:
$ sudo apt-get install -y xsane && xsane
