It might be fixed for earlier versions of Ubuntu but I confirm this also affects me with: - Scanner = Canon Lide 110 - OS = Ubuntu 14.04 up to date - simple-scan = 3.12.1
The process to repeat the bug is: 1- scan an image and save it 2- close simple scan 3- re-open simple scan 4- simple scan just hangs and nothing happens. It looks like it doesn't see the scanner anymore. It is important to close simple scan between scans (the bug doesn't occur if you scan multiple pages with closing simple scan).
